Harley-Davidson Performance Hinges on One Major Factor

Harley-Davidson performance hinges on one single factor that can make or break your build. Unfortunately it's just one big compromise if you don't like the style of exhaust that makes the most power. Same goes for the air cleaner, but the air cleaner isn't so much a factor unless you have a very large displacement at or above 120 inches. The exhaust that looks the best and sounds the best may not make the most power. Popular choices like 2 into 2 aren't the best at making the big power but, if they have a crossover you can get the best of both worlds. Great sound and power delivery like a 2 into 1, but that's just half of it.

What's your favorite exhaust? Do you compromise or just get what you want without worrying about power loss?

[@semperfipar1299]

I like the sound of staggered shorties where the exhaust pipe enters the small then the larger diameter slip on and at the end it returns to the same diameter as the exhaust pipe. It has a good old school deep sound. No nozzles needed. I agree on the cross over pipe giving more than enough exhaust. On a side note about intakes and knowing if you have enough. If the engine intake is drawing oil out from the heads to where you can see it drip you need a less restrictive air intake. Thanks for dispelling the myths of intakes.

[@69Busa08Nova]

That’s tough…LSR on my twin cammed softy, Thunderheader on my Evo RK, no idea what kind of slip ons and true dual on my shovel. Love them all though. Far as favorites, couldn’t tell ya.

[@jimbrady3675]

My favorite exhaust for look and sound is the Vance & Hines true duals for my 1999 EVO Springer. No baffles and the performance is fine with my Arlen Ness supersucker air cleaner and EV27 cam.

[@markpatrick7072]

Vance and Hines Pro Pipe

[@elliotstrong5953]

Form follows function. Fab 28 all the way for my Dyna💪👍

[@johndonkor243]

Personally, I think the elephant in the room is the tune. Most people don’t realize it, but there are a ton of misrepresentations when it comes to dyno numbers. That’s why dyno charts are for the birds. These astronomical numbers are done with 6th gear dyno pulls. Most good tuners will do honest runs in 4th or 5th gear. The other thing is that no two dynometers are the same. Some are very liberal with the numbers, and others are conservative. The truth is that the seat of your pants will always tell you how your bike is performing. This obsession with numbers is absurd.

[@livehardone9437]

Agree. Peak HP numbers are sort of irrelevant if you are not always riding in the gear and RPM where the peak HP is made.

[@breedlofam]

Exactly. My tuner tuned my bike to my riding style. I sacrificed a couple HP/Torque, but it's tuned for how I ride and gives me power where I want it and not 1000 rpm above or below where I normally ride. Chasing numbers is for nothing other than bragging rights if you actually ride your bike often. Who really wants 150+ torque immediately? I know I don't. I'd rather sacrifice some and hit it at 3500 rpm with a nice steady curve than hit all of it at 2200 RPM or not hit it until 4500 RPM

[@georgewetzel4380]

ABSOLUTELY

[@bradballard2068]

Old school 💪😊 I agree

[@Frankfoot986]

Let’s not forget about the people who buy fuelpacks and powervision a are a “tune”.

[@johnsb1550]

Harley engines are designed for torque and that's what I go with. I actually have a Vance and Hines original Pro Pipe with an original Cherry 🍒 Bomb muffler that I fabricated and with my modifications, the bike loves it. The amazing thing is that it actually isn't so loud that it has you talking to yourself while cruising but drop a gear twist the throttle and hold on...build for torque and HP will come...great video

[@PeterSmith-or3pq]

Love my V@H pro.95 " t.c.

[@jontiffinphoto]

ProPipe for the win, I refuse to give it up!

[@mmcclen9]

I built a Road King from a wrecked 2008 Ultra Classic with a 110-cu in SE engine. Built the engine with Feuling OE+ camplate and oil pump and Wood TW 7-7H cams (same as my 01 RK 95" with Wood TW 6HG cam with Rinehart tru-duals with 3 1/2" mufflers). On the 110 build I used S&S tru-dual headers with Rinehart 4" mufflers. I have never dyno'd the 95" RK but it is lightning quick and a stump puller. Had the 110" dyno tuned and got a disappointing 102-HP / 109-ft/lb Torque. Road the bike for a while then discovered DK Custom selling disc's that are installed in the end of the mufflers (work similar to torque cones). What a difference the disks made. Have not had it dyno'd again; however, seat of the pants tells me it is much better.

[@bddfc1968]

Absolutely Hands down for me I always do the 2into1 Thunder Header system for all my Twincam's paired with the target tune power vision systems

[@scottmorgan133]

Thunder header is decent, but it’s a midrange pipe that tries to pull again in the upper RPM. It’s mid way in performance. Their issue isn’t the muffler, it’s the collector merge. That’s the key in a 2-1, the merge.

[@bddfc1968]

Yup right where I like it

[@jeffuda3638]

Love my 2 to 1 short style bassani road rage on my 02 heritage softail 95 TC! It made the Jerry Branch performance set up another level! It did have the D&D dauls with a crossover pipe without baffles. The road rage is extremely loud on this bike with the baffle in it!

[@hawkdsl]

I have the V&H long shots with the hidden crossover for my Dyna. With the "quiet" baffle I'm making 115 hp, and I forget the trq, but its up there. Took allot of work and money with other combinations before I hit this set up, and I think it's perfect. It's incredibly smooth, sounds perfect without the "blat" of open pipes, and is just a sweet heart on long rides. Plenty of HP and TRQ to keep it fun without the over heating and hard starts of those "I need numbers!" bikes that no one has any fun on in the end.

[@GawgaCracka]

You're so right bro, as a Harley Tech I've seen so many people mis match performance parts that work against each other and then wonder why the numbers don't match the cash they spent ordering empty promises off line. Hope You had a Happy Thanksgiving as well my friend.

[@echo5226]

What do you think about Blow Performance Exhaust pipes?

[@kittycorner8526]

I went with Rinehart true duals on all four of my TC 96 HD's, but on my 4th bike, a 2010 Ultra, I also had the cams replaced. Wow! Big difference. California is making it hard to upgrade your exhaust, and expensive if they catch you. TAB Performance makes a good stock-looking header system too.

[@jackklarich7045]

Pretty good video, I will give you big kudos for not saying back pressure. Every time I hear someone use that term it proves to me they are not educated on exhaust flow dynamics

[@FXFBS540]

Rode my FatBob with slip ons for a few years. But now it's time to get rid of the Cat, and get a better looking exhaust. Ordered a stainless Bassani RR3. Being louder is a safety feature too.

[@1AXMRDR]

A 2 into 1 exhaust will give you better performance hands down. Thunderheader is my favorite. Sound and performance can't be beat, but it is a louder pipe. Get the longer pipe so the sound outlet is behind the passenger.

[@joeplem5329]

My V&H duel radius probably isn't the best choice for the 110 tire shredder kit but damn it looks and sounds rowdy AF!!!

[@upsidedowndog1256]

I am a fan of the Thunder Header exhaust. The picture of the W3 Feuling was cool!

[@thatguy8718]

this debte took me forever personally. i ended up going with TAB perfomance 2-1-2 with the 4" BAM sticks and Zombie baffles. I had BAM Sticks on my las bike and LOVED them!!!

[@timnevitt2993]

v&h 2 in 2 big radius for my bagger awesome sound

[@GixxerFoo]

Those are some awesome exhaust and they typically make 5 horse more than short shots.

[@leonardstanford1877]

You are exactly right with stock header pipes & aftermarket mufflers that's hard to beat ! I have a freind that's been dyno tuning for well over 10 years & he has showed me that fact many times !

[@rimaspazereckas2748]

Not sure on the cross over...it seems more of a middle ground between "true" 2-2 and 2-1 systems. Yes factory headers with a good set of slip ons can be amazing, my 2014 xl1200c made 90/90 with a stage one heavy breather and a set of v&h slip ons (now going down the 2-1 path, due to where it will be spending time in the rpm range) I am unsure about my 89 fxsts it will be sitting in the benifical 2-1 rpm range (highway crusing) but unsure of looks, the Rinehart 2-1 seems to look way to long (if it was a little shorter maybe)while i enjoy the looks of the Rinehart 2-2...

[@grayghost1423]

2 into 2 with a cross over. A win win for me. 2 of my 3 bikes have them. Grateful video.

[@300shields]

Which exhaust do you have, u have a heritage 2017 and was looking at Samson fishtail. Do they make a crossover so it can be a two into one into two? Thanks.

[@grayghost1423]

@300shields VH Longshots. The factory head pipe has a crossover built into it, this is on my 2020 Sportster Roadster. Cobra also makes a 909 Speedster, full exhaust with a crossover that works good.

[@roadking2054]

My 2012 Roadking has S&S power tune head pipe and SVT Boneshakers mufflers. I took baffles out and installed Thunder Toque Inserts. I love the setup.

[@capecodbiker9902]

💯 %. I did a 30/30 cam in my 114 I had a true duels system with Krome werks. I didn’t like the Dino numbers. I swapped out to a 2into one. S&S system I gained 12 hp and 8 torque with the exhaust. Definitely the exhaust is very important

[@xlr8r3VA]

Great info Gixxerfoo! I have V&H Staggered Shots on my 883 and they work pretty good. I pulled the baffles and installed a set of DK Customs 1 5/8" Thunder Torque inserts and I could feel a difference! It may be a small difference, but they work. The trick is getting rid of the reversion, that's what they do. So, if someone has the Short Shots, they are worth a try.

[@triumph951000]

My 03 FLH has true dual ceramic coated headers and Supertrapp mufflers with the discs and closed end caps !!! Runs beautiful and smooth all day long. I always Loved those mufflers. Saw them on an old BMW PD 1000cc and an HA with them on an FXR and had to run them myself when I made the system. Cruising along at 70mph you just hear the engine working and a warbling behind you. Never once cared about the "numbers" I just wanted it to take me and my shit wherever I want to go for as long as it takes and it does it all.

[@mr.b3168]

Can you do a video on the mag wheels having the pulley come off with bolts shearing? It seems to happen all the time on every forum or group

[@_hitmn_]

I recently upgraded my camchest on my 88ci. I def felt the gains but I'm running a true dual system with 39in mufflers and a big city thunder baffle. I bet if i was running a 2-1 system, i would feel way more gains. My tuner advised that to me and he was right. Thanks for the video again mate👌💪

Vance & Hines 2 into 1 into 2 with a woods 22xe cam, and a thunder max auto runner. Dyno results 120hp, tq 128 motor 107

[@timmcpeck7527]

That cam is a beast. Those numbers out of a relatively stock 107 are pretty impressive.

[@timmcpeck7527]

Stage 4 114 on my 2018. Went with a good cam and tune with powerduals and S&S Grand Nationals. Very pleased with the results after the dyno. I originally had the dresser duals on it but they did not dyno well with the whole kit. It’s definitely a constant learning process.

[@manmeetsharma2632]

When I bought second hand 2006 xl883, it came with v&h straight shots full system. I changed to factory headers and khrome weeks mufflers. Bike feels very responsive and pulls hard between gears. I also like the sound, it's very deep and mellow while cruising on freeway but loud while accelerating. V&h was loud all the times, it was tiring after a while. Volume at idle is same but very deep with khrome werks. It made big difference in way bike makes power.

[@jerryspencer5453]

I always have a tendency to lean toward Vance and Hines longshots 2n2. I have to have 2 mufflers on my dresser and dual fishtails on my Heritage Springer. Although, I do have Victory Performance Exhaust 2 into 1 on my Kingpin. I don't hotrod too much anymore so I go with the look and sound. Good info. Thanks man.

[@clubstyleridahd4695]

I've been playing with different baffle sizes and lengths for my hammer performance sportster. I've done 2.5" perf, 1.75" diameter /10" longreducer, 1.75" diameter / 2" long and now I'm running a 2" louvered baffle wrapped. It's crazy the differences between the baffles / inserts. Small reducers make partial throttle inputs very high in torque. The bigger baffles give it a lot more top end

The “best” exhaust is the one you a) like that also b) supports your configuration now and c) in the future. If you have a shop you like and (more importantly) trust, just ask them. If not, call Fuel Moto and tell them what you have and plan on doing and they’ll give you recommendations. For example when my warranty ran out and I did my Stage I I called them, told them it would be stage 1 only this year but that I planned on a 96 to 107 or 110 in two years, and that I was considering a Trask turbo a year or two after that - so they made sure I bought an exhaust that would support a turbocharged 110 while warning me that if I went bigger than about 113 (turbo) I’d need a bigger exhaust, but that doing so was so expensive I might as well go to 120 (the turbo would also require a larger air cleaner, but that Trask included that in their kit so not to worry about it). The best part? Not only did they suggest exhausts they sold, but also gave me a few models with very different styling that they didn’t sell but knew would work. Any salesman who will tell you when the best fit for your needs is sold by someone else is a salesman you can trust, but I liked their exhaust (and it’s price) so bought from them anyway. I’ve since also bought their 110 kit, had the, do the porting, increase compression, etc - all with great results (I did the install, they did the machining).

[@paulg5835]

Yeah. That’s solid. You don’t see many salesman doing that these days.

[@Rollie396]

This topic is what I think about when I wake up at 3am.the brain turns on and won’t turn back off. I put s&s power tune duals with rinehart slipons on my 88. When I had the 88 built to a 106 stroker,my builder wanted me to put a dnd 2-1 on it. I decided to stop the bleeding there and stuck with the s&s just to save some money. I still think about swapping out but can’t make the decision to do it. I know I’d gain a bit more,but do I reaallly need to?I like how it sounds as it is. It doesn’t sound near as vicious as my wife’s 110 roadking with the 2-1 pro pipe,but it does sound nice and I like the power (more is never a bad thing though).This is the debate that’s been goin on in my head for a very long time.

[@gvs5318]

Thanks for your exhaust input and I hope in the future you visit indepth the old adage of: "There's no replacement for displacement". I installed a 131 crate motor with the recommended super duper Harley downpipe and Khrome Werks slip ons. So far so good but I must admit having outgrown the Stage 4 Harley upgrades and am considering the 22XE cam. I've watched your cam video and hope you can revisit this winter sometime the pro's and con's of different cams in big bore, (131 and up), applications. Thanks in advance

[@simongilbert2704]

yes , you are right , really short pipes can rob up to 20 bhp and just make noise , countering any hop up mods you have done to a large extent , unless you have a flow chart for your bike [ no one has ] its a common sense approach to try and match all the parts ;;

True duals are the worst exhaust system for any performance bike build. They have no exhaust scavenging. I agree that two into one is the best for performance and a dual system with a crossover is the next best thing. And thank you for telling the world what I've been saying for too many years, V&H short shots are the absolute worst exhaust system for a performance build. I call them slow shots...

Hands down nothing can compare to any 2 into 1 exhaust.

[@RufusCapstick]

The question is why, I have a Stage 2 Twin Cam Springer and tbh it's a death trap, with more power than the spaghetti frame and bicycle brakes can handle. I bought a rice rocket for less money than just the Stage 2 and it's a missile on wheels, handles like a dream. Imo it's a Weiner waving, pissing contest, driven by the aftermarket, with people thinking they need more and more power. I also have a 300cc bike with 33hp that does everything I want, including 2 up riding.

[@bradwilliams4921]

If I had a Touring Harley-Davidson my biggest concern would be how it sounded to me.

I went with the 2 into 1 rhinehart on my stage 4 107. It’s loud and slappy sounding on the lower rpm range which I don’t especially care for . It sings higher up. Stage 4 is about performance. Anything other than 2 into 1 is out of question regardless of sound.

[@araneaetvelivolum1086]

I'm in the process to get S 1 for my 2020 FLHTP. My decision is an outlaw 606 air cleaner with transformer EBS from DK Custom as I like to reuse my air cleaner cover . Head pipe from tap performance 2-1-2 and slip ons 4.5" from Sharkroad with 2.5" baffles. Tuner I'm undecided. V&H claims that you can load custom maps into the FP4 in the future which I need as I want a S&S S2 475 gear kit afterwards. First autotune and then when S2 is installed, get it properly tuned. Avoids the double tuning cost. On the other hand, a power vision is a safe bet and worked well on my old bike. What's your take on this subject? Good video, ride safe 🤙

Pushing 116 HP/125 Tq

[@davidcarroll7193]

I have 14 flhxs with a d&d fat cat and a Arlen Ness snorkel and a FP3 the rest is stock for now, can I get to much airflow? It pops sometimes when shifting.

[@berube361]

Harley performance hinges on one factor. Having super deep pockets otherwise you get nothing lol.

[@koolaidacidkilla179]

Any inputs on this t.a.b. exhaust for baggers? Kinda pricey but I've heard good things. Lmk!

[@Ken-wu6hr]

I have a 08 Electra Glide Classic. I’m wanting new slip on’s thinking Tab 50 cal with Zombies maybe air filter. What tuner do you recommend? I would like it to be Flexible. If I decide to change cams ect. Thank you Btw I only have 8000 mi on it.

[@hotrod5853]

I have same bike, get rid of the factory header, go with a true dual exhaust and what muffler you like, I went with V&H, nice low end sound and on highway they settle down and not annoying. Also do stage 1 and you will be happy. Well I am, all I need. Cheers.

Vance Hines

[@user-iu8eo8lh2u]

I have the Vance and Hines two into two big radius without baffles. Can someone tell me what I’m gaining or losing with them? I don’t care about horsepower I’m looking for more torque. Going to add DK Thunder torque inserts. Thoughts? Any comments/reply would be muchly appreciated Cheers 🍻

[@Heritagejim5339]

Gixxer got a stupid question, if I’ve have a slip-on, and want to go with a 2-2 crossover do I have to spend another 400 bucks for another Dyno run?

[@MidnightSportster]

2017 SE stage 4 roadster with 585 cam sndbi have powervision 3. Im exhaust shopping now. I have short shots and they are definitely not staying. What would you recommend to maximize power/torque? Looks and sound be damned this buildnis purely about performance at this point. Im going to hit the dyno this spring.

[@Chris-gi9ch]

I haven't even bought my first Harley yet, but I figure if I see %90 of %1ers going with the Thunder header? I can't possibly go wrong........

[@paulg5835]

It all depends. I’d say the one percenters on Sons of Anarchy prefer the Thunder Header. However I believe when you look at the Mayans MC that number will be substantially lower. I guess it just depends on how loud the exhaust has to be to drown out the sound of gunfire when they have shootouts on the interstate.

[@Chris-gi9ch]

@@paulg5835 Personally I like sound from V&H, but I have heard of quality complaints? I would probably go with the Bassani Road Rage! 😉

[@paulg5835]

@@Chris-gi9ch Glad to see you can take a joke. Hope you get your Harley soon man.

[@peterbergeris6510]

I have a 2008 Softail deluxe with Vance n Hines exhaust. The rear exh sits at the height of the rear brake caliper. I couldn't get the passenger pegs I wanted so I compromised. I'm thinking on cobra true duals with billet caps. What do u think?. I like exh on each side of the bike but don't like fish tails.Dont need excessive hp. Highway riding only. What do u think of Arlen Ness 90 ° velocity air cleaner? Drag specialities has it for $308 n titan customs for $300.

[@infini1970]

My big issue right now is if I'm gonna be disappointed if I do the Screamin' Eagle Twin Cam Conversion Kit - 96CI to 103 CI since I already have the Woods 222 cam and , great intake, V&H two to two pipes and tuner. It's way way better than stock already but just drags at times in my opinion. I'm not sure if the kit would make me happy lol. The S&S 110 kit is way more expensive.

[@sbhjackson5931]

I just did the S&S 107 kit on my 09-street glide with S&S 585 cams D&D 2 into 1 exhaust with the perforated wrapped/medium baffle. 10.5:1 compression pistons. The exhaust is a little louder than I'd like but the performance difference is nice, (mpg not so nice) only thing is that I have to run higher rpm's to feel that extra performance. Going to a 107 may be the way to go for you also. Good luck.

[@Clutch_Kick187]

I have an recommend the fuel moto 107 kit on my 2010 street glide.. I used S&S 585 ez start cams though, instead of the woods they usually use. The 96in heads don't have ACR (auto compression releases) so I wanted cams that wouldn't require installing compression releases, or burning up starters. New Barnett clutch to hold the new power, and I also upgraded the camplate and oil pump to a fueling OE+ as there was scoring inside my factory pump, the oil pressure is amazing now. That kit is under $500 it runs great.. 111hp & 119tq.. I will do the heads at some point in the future but this combo is working out great..

[@sbhjackson5931]

@@Clutch_Kick187 I have the manual compression releases, also changed to a high flow oil pump, new cam plate & cam chain tensioners. I didn't get a new compensator or clutch because funds were running out fast and from my understanding with the HP and Torque I should produce they weren't really needed. I still need to get it on the dyno to get it tuned just right and also curious to see my numbers.

[@thomasborger6548]

​@@sbhjackson5931 you have good components, if you can find someone that tunes well there is no reason for mileage to suffer greatly. Good luck

Harley-Davidson secret is performances simple dinero money that's all you need

[@bmwdan3445]

I know this is off subject, but whats your opinion on adjustable pushrods versus taking the valve covers off and using the stock pushrods when replacing a upgraded cam?

[@1AXMRDR]

Adjustable pushrods are good to have. Buy them once and use them forever. Saves a lot of time and money when you change cams or replace lifters.

[@breedlofam]

Stop making these decisions yourself. Performance is greater than the sum of its parts, it's how well those things mesh and work well together. You can spend $$$ on the best intake, cleaner, cam and exhaust, but if they don't work well together, you're leaving power on the table. A great tuner knows what works the best together, ask them. Then order from them if you can as a token of appreciation for their help. What parts you likely have in mind aren't going to be what they recommend.
