How To Install a Full System Exhaust for Harley at RevZilla.com

[@TilemachosSheva]

I don't own a Harley. I don't even own a "big cc bike", I don't know why I'm watching this, but it is awesome. I like this guy!

[@TheUnendingJourney]

If you add another 0 onto my displacement, mine would be a big cc bike :) 150cc XD

[@Maxtowers71]

well, Lemmy is the man... i've actually done this a couple years ago, but i'm here watching this...

[@Lighteye67]

Lemmy makes it so easy to learn. Minor wrenching activities like these are EXACTLY what I enjoy doing. Thanks for helping me take care of my FLHR. Yes, I'm an RZ repeat customer, and Lemmy's one of the prime reasons.

[@NICKBALLOON]

You guys should do a how to install bars and cables. please!?

[@Redeemed427]

Thanks Dude, it makes is alot easier when someone tells you, okay, EACH pipe has 2 bolts at the head, 2 bolts at the back, and 2 clamps on guard. Simple details makes it alot simpler for those of us that have never did the deed. Also, the warning about the clips that hold the head collars on.

[@rclines001]

Pretty important to tighten exactly like he said. You start just cranking everything down as you go, and that causes binds in the exhaust and unwanted vibrations. Chances are if you have a vibration that concerns you, it's because the exhaust was installed incorrectly. You may be sitting there thinking "but theres no leaks, so that can't be the cause of MY vibrations", but you'd be wrong. I've experienced it myself. Then after I loosened everything back up and tightened it all back down in the correct order, the vibration vanished.

[@bill-2018]

I appreciate this video. I'm replacing the front exhaust gasket and managed to get the pipes off after struggling with rusty nuts and threads. A new gasket later and a problem. I knew there must be something missing. I need the spring clip at the engine. The cheap Haynes manual is bad, all it says about the exhaust is an oxygen sensor. I knew I should have bought the proper Harley manual. I still might.

[@NothingToSeeHere12345]

I've got the Crusher PowerCell Staggered Duals after market exhaust ready to go on my Switchback as soon as a leg injury heals enough to let me get back on the bike. Glad this video is here to walk me through it so I am confident when it's time to actually get the install done. A trick that someone mentioned on another exhaust install video is to use the spring flange retainer clip to press the new gasket in. Gets it nice and flat. Something I'd love to see RevZilla do with after market exhaust reviews is a decibel meter reading. Get a reading of the stock exhaust at say 3 feet out from the back end of the bike, then a reading from the same distance with the exhaust being reviewed. Maybe with readings at both idle and mid-range RPM. I've got my exhaust all picked out and purchased, but something like that sure would have made the process a little easier.

[@Savage1776_]

This is one of the best channels for bikes...there are far a few

[@St3Vi3123]

Can you guys please make a video about changing stock bars to mini apes/changing cables on an Iron883? That's the only thing you guys haven't done!!

[@tobiasjohansson7751]

Thanks for the help, had to change back to the "Tommy Guns" on my fat bob to pass the inspection due to ridiculous 95 db-boundaries here in Sweden. Gonna change back to my V&H tomorrow and this helped a lot 👍

[@jamesarone3076]

I just picked up a 2012 dyna wide glide and plan on getting a set of V&Hs for it did you just need the fuel and the pipes? Or is there something I'm forgetting?

[@tobiasjohansson7751]

@@jamesarone3076 To really make you Harley perform as it should/could you need three things; better airflow, cleared pipes and some sort of software for controlling your fuel. I also benched my bike to get more power where you want it, but that's usually not needed while I still really recommend it. So a hi-flow air filter, a software mapping, some straight shots and some money... Have a great summer 👍🏻

[@robax]

Excellent video in every way. If they're all like this on this channel then the people behind them deserve some real kudos.

[@JoeMegg303]

Im new to the motorcycle world and Ive adored Lemmy and his videos. Very engaging and helpful! I wanna have a beer with him.

[@eltapatio95]

I just purchased a 2008 Harley Davidson nightster 1200, the previous owner put on aftermarket exhaust and aftermarket air filter. I asked him if the motorcycle had a tune and he said it did not. Is it a must to have a tune on it? Is there any chance of the engine getting damage without a tune? It only has 6,000 miles. Thanks for your time :)

[@Djbutta23]

The only video I found that addressed th C-clamp issue.

[@robertmcmahon6061]

NEVER tighten exhaust mounts UNTIL you torque flange nuts....upper nuts 9-18 inch pounds, lower nut to 120 inch pounds, then upper nut to 120 inch pounds. use hi-temp anti-seize on studs.

[@Jtdubbzz]

I just installed the V&H 2-1 comp exhaust the other day but had to pull the muffler off to change out the mounting bracket… I tightened the muffler first and then the flanges… rode great yesterday but today I checked on em and they were pretty loose based on “hand torque” so I snugged em up, afraid I overly tightened em and crushed the gaskets because they were still kind of hot but didn’t get too crazy, either way I took a ride this evening and was noticing some unpleasant vibrations in 6th gear so I just loosened everything back up and went headers down… I’m hoping this does the trick… I’m noticing some trail and error here lol. Shit! 😆

[@CrazyNick-nr7kk]

Is it worth putting lock tight on the bracket bolts? Also this video doesn’t mention it but it’s important to torque down bracket bolts and sprocket cover bolts to the correct specs.

[@SuperSnallygaster]

Lemmy, you didn't warn a brother about stubborn exhaust gaskets! They frayed when I tried to pull them and the one in front cylinder took 2 hours to get completely out! Also, studs and flange nuts were super rusty for a 3 year old bike.

[@Askatechannel]

Lemmy you are the man! Quick question though, if I install an aftermarket exhaust and air cleaner without using fuel pack am I likely to run into problems? Thanks

[@RevZilla]

Yes, you'll take a bike that runs lean stock from the factory and make it run even leaner (hotter). That's not good for overall engine life, and you won't make the power you're looking for. -DrewZilla

[@IAmWoody]

Just finished my V&H Grenades exhaust install on my 883 Iron, with help from this video. Thanks, Lemmy!!

[@Malignantt1]

I have the same pipes. I think its leaking. Its really hot near the heads even though I cant feel any air puff or move anywhere, its still very hot air. The o2 sensor area is blue/purple. It smells like exhaust really bad. Dont know what to do. Stock exhaust wasnt like this

[@manuel3045]

@@Malignantt1 maybe muffler clamp. In the video towards end he mention leak i think he mentioned leak in beginning too

[@yingbopanlaque5713]

Do you need to always tune or a necessity to tune/modify your fuel sensor, evrytime you change full system exhausts and/or slip ons?? , and if i dont? if just change my exhausts pipes, will it harm my engine? thanks..

[@RevZilla]

+YingBo Panlaque Yes, every time you change your air intake or exhaust, you are changing your air/fuel ratio, which means you need to "tune" the whole intake-combustion-exhaust system again. Even if you just change your exhaust, you still need to change your fueling. If you don't optimize your fueling, your engine will likely run "leaner", which means the engine will run even hotter than it already does. Over time, that's not good for the engine. -DrewZilla

[@yingbopanlaque5713]

Thanks for the fast reply, follow up question, theres no harley service center in our place, how do you suggest i do the tuning? I mean , can i do it myself? Thanks again

[@dannydamico7312]

[@Kusgan4x4]

thanks for the tip!! though mine is a Vulcan it's pretty much the same concept.

[@yinyanglovebomb]

youre the man lemmy!

[@Bwvikingbiking]

The exhaust gaskets used in video were race style flat gaskets do not use them with a tapered collar on the primary make sure to use a tapered gasket to ensure seal.

[@billbyrd9845]

My 2018 exhaust pipes are joined with a welded-on crossover pipe. They obviously have to be removed together.

[@yoshimitsu411]

Great video but I thought the stock exhaust sounded better :)

[@xldh44]

I have an '03 HD XLH 883 Sportster (6k miles, mint condition.) I'm planning to install Vance and Hines, full exhaust, staggered short shots. Looks DO matter but this move is for enhanced performance; I am not into loud at all. I'm also planning to get the VnH quiet baffle but considering the super quiet baffle. So here's my quandary; I'm not too keen about spending 5 bills for this boost I anticipate and spend another fifty to choke it all out. How much performance would I sacrifice if I went with the SQ baffles? Love your videos Lemmy! Very informative and a big help. Be safe.

what happened to working at Teller-Morrow you made Jax think you were dead to get out to start your own garage

[@xaviervazquez910]

What about the o2 sensors. Seems like an important piece to ignore on this.

[@RevZilla]

Most full exhausts we carry have bungs and adapters to fit both 12mm and 18mm O2 sensors, so you can plug your stock O2 sensors into the new exhaust. Popular fuel tuners like the Fuelpak FP3 require the O2 sensors for proper fuel remapping. -DrewZilla

[@MikeCuthell]

Yeah I found the O2 sensor on the front, that was a nice little surprise.

[@mtp04987]

He talked about the 02 sensor.

[@CovenantAD33]

Glossed right over the part I’m struggling with. One of the flange bolts/nuts seems impossible to reach. The one to your far left when facing the bike.

[@jsandrieux]

I ordered a 135ci Crate Engine from the HD Dealer to have it installed on a 2022 Street Gide Special. To maintain the warranty on the engine, I need to purchase the Oil Cooler/Fan Assist, a Screamin Eagle Performance Tuner, and a complete exhaust system from D&D. Do I need an upgraded transmission to maintain my warranty on the bike and the warranty on the new engine?

[@towelie4625]

Do you have to do something with the battery before you remove the oxygen sensors?

[@MegaVinny73]

Hmm, do you use sensor plugs if using an FP3 or do you reinstall the sensors, the V&H pipes have ports for right? Also the large hex on the cover over the front sprocket, whats the size? I've tried a 5/16 and its the closest but doesnt slot in. I've tried imperial and metric keys and nothing seems to fit! And what about bolt torque settings, cant find them anywhere either. Cheers...

[@intillanes]

Great video. I'm getting everything from Revzilla for my 2022 Iron Sportster. I have a question for you. I'm replacing the pipes for Cobra Short RPT. I bought the FuelPak3 from you guy already and will install it permanently in my bike. Should I connect the Oxigen sensors when installing the new Cobra pipes?

[@lukealvarez6161]

Great video Lemmy; one question, if you don't put a stage 1 or 2 hi flow intake, the engine won't run lean because the intake will only allow the OEM stock amount of air, so why would a tuner be necessary?

[@teresinacambiotti]

Did you ever get the answer to this? I'm wondering the same. I'm putting on a full exhaust system but never changed anything else. Still stock. Do I need a tuner?

[@jerryhelm5118]

I own a sporty loving it....great job guys ...love the videos...

[@thirtytwoforty]

Can you please do a video on removal and install for pipes on a 2016 Forty Eight! They've changed some shit and really made it quite difficult to remove the stock system. I'm having a hell of a time trying to get mine off.

[@thirtytwoforty]

The way it looks, I have to remove the brake Slave cylinder? I think it is, then the sprocket cover to gain access to 2 hex bolts to remove the bottom bracket of the exhaust at the cross pipe, they've connected both pipes together. It's a whore of a job for a beginner. I did my 2012 iron with no issues at all. This is not the same cake walk.

[@RevZilla]

+Brad Meyers We aren't able to produce installation videos for every motorcycle, but we are working on a video series detailing common Sportster modifications, so you may be in luck. This won't be immediate however, so in the mean time, you may want to grab a factory service manual and/or consult a Harley Technician. -DrewZilla

[@WilliamRahl]

Loved watching the levels of lemme’s drink rise and fall haha

[@SuperSnallygaster]

Hey Lemmy, thanks for the great video. Is the process basically the same for HD Touring bikes (2015)? Obviously I'll have clamps and O2 sensors to deal with, but are there any other things to look out for? Thanks!

[@imaquis8368]

Love these videos really wish you guys would do a review of the Iron 883!

Can you show a full install on a 2018 114 fat boy? I can’t figure how to get the front bolt off? Is there a special tool?

[@albertogarciawoodfield1856]

I had real trouble removing the gasket on the front cylinder head, it was literally stuck on and took me about an hour to pick it all out. The front cylinder head where the gasket goes seems a little rough compared to the back although I’ve removed all parts of the old gasket. Will this still seal or is this a problem?

[@acealv8788]

Do you use any copper grease or any exhaust paste ?

[@tombooze74]

I noticed you didn't use any exhaust paste. Is this because the gaskets and flange are being used or because of the type of exhaust being used

[@RevZilla]

The exhausts we carry do not require any kind of paste or putty to install, but we do recommend using fresh gaskets. -TeamZilla AJ

[@maurofmoreno78]

Should change forward controls first or change the market pipes for louder pipes ?

[@RevZilla]

If you think forward controls will be more comfortable for you, then do comfort first then pipes later. -DrewZilla

[@chrisdmcatee]

So if I use fp3 I don't need oxygen sensors? Sorry if this is a stupid question, but I thought that's how I understood it. If I have aftermarket fuel control, then I won't use o2 sensors?

[@RevZilla]

With the FP3, you do need to use your O2 sensors. If you want to take advantage of the FP3's auto-tuning feature, you need the data from the O2 sensors. -DrewZilla

[@sabatonotaro1064]

Great video love this channel...Im unsure on the bung plugs? If im installing mini grenades, an air filter and an FP3 do i need the bung plugs??

[@RevZilla]

No, with the Mini Grenades and the FP3, you will use the stock O2 sensors, so you don't need bung plugs. -DrewZilla

[@sabatonotaro1064]

Awesome thanks!!!

[@CarlosDiaz-sj8lm]

I installed mini grenades into my 2015 Harley 48. The exhausted flanges wouldn’t properly seal. But I did not feel any leaks. Is this an issue ?

[@dimedude]

Newly subscribed member to the Revzilla channel, great videos - 1 question if I may, should the flange sit flush against the head? I can get the width of my finger between the flange and the head, is that right?

[@RevZilla]

So after speaking with Lemmy a bit, he said that no, the exhaust flange won't necessarily sit flat to the exhaust port. The key is for the short amount of pipe ahead of the flange to seat into the exhaust gasket. -DrewZilla

[@dimedude]

Perfect, thanks for the advice thats what I am getting - with no air gaps at the head, so it looks like a good install thanks to Lemmy and RevZilla \m/

[@Stacker_Actual]

What size are those nuts? Lost one and don’t know what size to buy

Awesome video. Just got this exhaust for my 16 Roadster, but it didn't come with a new muffler mounting bracket. Do you guys sell those? Or do you know where I could get one? I can't seem to find them anywhere. Thanks!

[@RevZilla]

If you need OEM parts, you would need to go to a Harley dealer. If you're missing a part from the aftermarket exhaust's part list, then you would want to contact the dealer from which you bought the exhaust (either us or someone else). -DrewZilla

[@havikplayz]

Do you have a video for putting stock exhaust back on?

[@1001UFC]

At 3:13 you note that as long as you have an after market Fuel pak, you do not need to reconnect the oxygen sensors. I followed your recommendation and now the Fuelpak 3 is giving me an error, as well the engine light is on the stock odometer. So, question is, assuming the oxygen sensors do not have to reconnected, how should I clear the light on the odometer as well have the Fuel pak 3 stop telling me I have a problem with the oxygen sensors? Thanks in advance for your reply.

[@RevZilla]

I think there may be a little misunderstanding. If you listen at 3:13, Lemmy says, "we don't have oxygen sensors on our bike either, because we already have an aftermarket _fuel controller_ on this bike that deleted the factory oxygen sensors." In this install video, Lemmy did not use a Fuelpak FP3. He used a different fuel controller (in this case, a Power Commander). The Power Commander required removing the stock O2 sensors. Conversely, the Fuelpak FP3 requires that you use the stock O2 sensors to function. Your exhaust should have O2 sensor bungs, so the solution is to screw the O2 sensors into the exhaust and make sure the sensor wires are connected to the wiring harness. Your FP3 should then function as intended. Hope this helps! -DrewZilla

[@1001UFC]

I think the misleading part for me was that it said my "after market fuel controller" and I incorrectly assumed it applied to all after market controllers. Any way, took the exhaust off this past weekend and install the Oxygen Sensors and engine light is gone. Thanks for responding back.

[@waylandsworks]

thanks for the video. I installed power duals on a 2017 road king. I was wondering if the head pipe flange should be flush with the head?. I seem to have a little space between.

[@RevZilla]

Did you remove the original exhaust port gaskets before installing the new headers? -DrewZilla

[@waylandsworks]

No its brand new so i didnt think i had to and the instructions said "if needed" and I didn't watch this video till after.🤕

[@waylandsworks]

Ok great. Thanks for the feedback. Your reviews have been helpful. My 2017 Road King is running like a champion with the V&H fp3, power duals & oversized slip ons. Making the choice to install these was easy thanks to your videos. Now I just need you to do a cam install video on the m8.😆 Thanks again.

[@Spriterom]

Can the slip on exhausts have similar performance gains as the full system exhausts, for example screamin eagle street cannons or Vance and Hines twin slash with quiet baffles?

[@RevZilla]

Generally, no, slip-ons can't have the same gains as a full system. -DrewZilla

[@bwr1023]

I have installed new Cobra head pipes as well as Cobra slip on mufflers on my 01 road king classic. I cannot seem to get the front pipe tight. that is when i tighten the two nuts that hold it to the head it will still vibrate at the head. I have taken the pipe off and re-installed it several times with new gaskets each time. What could i possibly be doing wrong.

[@TigoAugustus]

You mention having to replace the studs. I noticed one of them was broken clear of the block while replace the oem exhaust on my 2006 roadster. Is it an easy fix I can do at home? If so, is there a video, or forum, you could recommend?

[@RevZilla]

It is not easy, as it requires taking it to a machinist for a replacement stud to be installed. -DrewZilla

I really want to do it myself and wondering if someone can give me some useful tips. Just spoken to HD dealers and they're talking about 2k, but as I said I'd rather do, whatever I can, myself and get the final tuning or whatever from there. They said I also need to replace the air filter and tuner as well. Any help will appreciate.

[@upup209]

Looking at doing similar. The more research I do the more confused I get. I found the HDforums the best source of knowledge and recommendations for products. Comments I have heard that have encouraged more research 1/ Crossover pipes generate the best sound 2/ mixing brands of airflow filters , pipes, requires self tuning for mapping on the Fuel Cell which takes two full tanks and the bike runs rough during it, but works well when mapped. 3/ Re-mapping a bike always starts from scratch. Hope that helps. I'm still learning

[@koreyvanhuis5716]

If you are using an FP3 to manage your fuel after doing a full exhaust instal will you oxygen sensors be necessary?

Hey Lemmy, great video. would the fuel pack void warranty?

[@RevZilla]

Different dealers have different interpretations of the Harley warranty, so it's best to first check with your dealer. Some are fine with it. Others aren't. You might also want to contact Harley corporate for the 'clearest' information on the warranty. -DrewZilla

It depends on the specific exhaust you have. Some mounting locations and clearances have changed between those two model years, but not all exhausts use the same mounting points or have the same clearances.

What do I have to do different if my sportster has ABS (2014 - new models I believe)? Remove the the foot controls completely? Any advice will be great, as I'm trying to install now. Thanks!

[@RevZilla]

It's possible. The instructions included with your exhaust should detail the process for you, since there are a lot of variables depending on the specific exhaust. -DrewZilla

[@TheAnnoyingBoss]

So if you need to modify your fuel sensor to allow more fuel, does that mean that full system exhausts give your bike less fuel mileage?

[@RevZilla]

TheAnnoyingBoss Sometimes yes and sometimes no. If better fueling allows you to run more smoothly at low RPMs, you may be able to run a gear higher and actually get better fuel mileage overall. And if you program the fuel controller to run a little leaner just at highway cruising speed in top gear, you can be more efficient. In the end, it all depends on how you ride the bike. -DrewZilla

[@TheAnnoyingBoss]

RevZilla Thanks. nice to know!

[@ricardoabrego3185]

What do I do if my mounting bolts to the exhaust bracket won't screw in? It seems like the inside is worn out. I bought my sportster from a dealer, not even 4 months in all the bolts fell off. I'm a new rider so I didn't know what was going on. I lost a few screws, and some screws literally screwed up the threads. So ya.... what do I do lol?

[@Idahoprepper1]

Since I have a 2016 fxdwg, and I ordered the FP3 and the big radius 2 into 2 pipes, am I hearing correctly that I use the stock O2 sensors when I put the new pipes on with the FP3?

[@RevZilla]

Yes, with the FP3, you use the stock O2 sensors with the new exhaust. -DrewZilla

[@mattrenfro857]

will my fuel system have to be modified if I'm swapping out for a different OEM system? I've got am 08 sportster 1200R and I want to put on a factory system from an 2016 48. Any ideas if that will even fit?

[@RevZilla]

Those bikes use completely different exhaust mounting points, so installing an exhaust from a Sportster Forty-Eight would likely require additional fabrication. Most modern bikes will benefit from fuel management, but we strongly recommend it when adding an aftermarket full exhaust system and/or a high-flow air cleaner. Most OEM exhaust systems are specific to the motorcycle, and should work with stock fuel mapping. -TeamZilla

[@anthonylockridge5652]

For that oxygen sensor, would I plug that back in once I'm done installing the pipes?

[@RevZilla]

Yes, you would reinstall the oxygen sensors after installing the pipes. -DrewZilla

[@fathertyme23]

What is the reason for unplugging the oxygen sensors? Asking for a friend

[@77cuti]

I have a 2012 electra glide ultra classic 103 6 speed. I bought v&h true dual with big Louie slip-ons also I bought the fp3 since I have the fuel pack do I need to eliminate my oxygen sensors

[@RevZilla]

No, you still need to use your oxygen sensors, so that you can take advantage of the FP3's Auto-Tune functionality. The Vance & Hines Dresser Duals have bungs for the oxygen sensors, so be sure to use them. -DrewZilla

[@MattCA88]

I have an 07 softail and I just bough Vance & Hines Big Radius with the FP3. So I still need to keep the O2 sensors correct? (no bungs)

[@guscya2020]

hi lemmy, if i was to install a an exhaust system would i need to tune it afterwards? i have read quite a bit that you dont need to tune for and upgraded exhaust.

[@RevZilla]

Lemmy put together two extensive articles on the subject and I will link them below. Long story short, if you're doing a slip-on exhaust, fuel management is not required. If you do a full system upgrade including headers, it is recommended. -TeamZilla Chris *www.revzilla.com/common-tread/motorcycle-exhaust-101 *www.revzilla.com/common-tread/fuel-management-101

[@guscya2020]

really appreciate the response. thx!!

[@vijaykishenhampapur8207]

Thanks Lemmy. Did my install yesterday, but the exhaust gasket got crumpled a bit when pushing it into the head on both front and back. Is that ok or do I need to get new exhaust gaskets - I did order the one specific to my bike , a 2015 harley 48 .

[@RevZilla]

The gaskets do deform when you tighten down the header pipes, but they shouldn't crumple when inserting them into the head. Did you remove the stock conical gasket from the head before installing the new gasket? -DrewZilla

[@vijaykishenhampapur8207]

Yes I did remove the stock gasket, using a pick. The new one just didnt go in smoothly so it crumpled a bit and I smoothed it down with my finger. I dont see any obvious signs of leaking exhaust gas from the header

[@RevZilla]

If you don't have any leaks, you should be fine. -DrewZilla

[@vijaykishenhampapur8207]

Thanks.

[@kylebarrows4676]

what about re-jetting? do i need to?

[@ujesse01]

I love this guy! Do you teach at an MMI or something?

[@RevZilla]

+Jesse Utterback He teaches strictly in our KZbin videos. ;-) -DrewZilla

[@LILORIONVDIESEL]

I'm trying to install my new drag pipes on my '94 sportster 1200 but I've ran into a problem with the bolt that sits near that rear brake fluid "box" and my forward control arm. Have any suggestions for me?

[@RevZilla]

If the forward controls are aftermarket, clearance may not be guaranteed. Therefore, you may need to get creative and modify something. -DrewZilla

[@LILORIONVDIESEL]

+RevZilla Okay gotcha, thanks for the tip

[@veteranswhobuild]

Great video, thank you. Two questions: 1. I have a 2017 iron 883 with ABS and am looking to install the V&H Shortshots staggered... does my ABS affect anything differently than what is shown in the video removal/install? 2. What type of gasket material (i.e. graphite wire) and nut type (i.e. chrome acorn) is recommended to use? Referring to the James exhaust gasket kit.. Thanks!

[@RevZilla]

ABS doesn't really affect anything significantly during installation. As for the accessories, it's really personal preference. A number of Harley riders here prefer graphite wire gaskets and hex nuts. -DrewZilla

[@veteranswhobuild]

Hey- I have one more question I hope you can help with, that was kind of skipped in the video! In regards to the 02 sensors: if I will be installing the FP3 at the same time as the exhaust, then I will need to disconnect the sensor during install (regardless), use sensor plugs in the 02 sensors, and then simply reconnect the harnesses as it came stock? Just a bit confusing at around 3:15 when Lemmy mentions deleted oxygen sensors due to the pre-installed FP3? If you can please clarify, that would be much appreciated! Thanks

[@micheljanssens]

@@veteranswhobuild Did you get an answer on this question. I have the same problem while installing e new exhaust on a sportster 2012 ...

[@moorshound3243]

Hi what fuel controller would delete my O2 sensors, & do I really need to do a delete if I'm putting on a set of V&H slip on's? Thanks.

[@RevZilla]

None of the tuners we carry specifically delete your O2 sensors, but you don't actually need to delete them for slip-ons. -DrewZilla

[@Sens3lesz]

Hey man quick question hopefully you can help me. I have a 1993 harley davidson sportster 883 xlh 883 and i want to put an aftermarket full exhaust its a carburete. I just want to know what else do i need to do or change to put an after market exhaust on it. Thank you.

[@RevZilla]

With an aftermarket full exhaust, you'll need to re-jet your carburetor with a jet kit. -DrewZilla *www.revzilla.com/motorcycle/dynojet-recalibration-jet-kit-for-harley-1990-1995

[@TheTim380ibew]

Lemmy, do you guys actually install exhausts at your Philadelphia location?

[@RevZilla]

No, our Philadelphia Showroom does not have the ability to install hard parts. If you have any other questions or concerns, please reach out to our Gear Geeks at 877.792.9455 or [e-mail]. Ride safe, -Pat www.revzilla.com/philadelphia-showroom

[@markw9285]

Very well produced video.

[@PRBalex19]

Serious question, my Harley dealer said if I swap the full exhaust with a TBR 2-1 exhaust on my 18 FatBob. I need to do a stage 1. Is that true?

[@RevZilla]

If you install a new full exhaust, you will need to retune the fuel mapping, but you don't necessarily need a new air cleaner. -DrewZilla

[@asessins7634]

Thank you Lenny excellent video

[@latestupdates5058]

Hi Dude. I got one question. Can i fit 2013 Dyna Vance Hince short shots to 2013 Iron 883. I look forward hearing from you. Thanks

[@RevZilla]

No, they're totally different engines. An exhaust for a Dyna will not fit a Sportster Iron. -DrewZilla

[@ghxulish]

7:11 i thought he said bum plug

[@patmanwainwright3423]

Hey Lemme ive notice that all exhaust VLOGs on RevZilla say its only leagle in califorina for racing and not on highway is that true for all exhaust or is RevZilla just covering its basses just in case

[@RevZilla]

It's generally true for _most_ exhausts. However, Vance & Hines and Yoshimura do offer California-compliant exhausts with breakdowns on their sites. Take a look at the links below. -DrewZilla *products.vanceandhines.com/?filtering=1&filter_regulatory=arb-california *www.yoshimura-rd.com/emissions-compliance/
