WHATS THE SECRET ? ROAD GLIDE Harley Davidson AMAZING EXHAUST SOUND

[@WORKHARDRIDEHARDER_]

Exhuast. When it comes to exhaust pipes. The smaller diameter of the pipe the faster the pressure wave travels down the pipe. This is why the twin cams with smaller diameter straight pipes had such a loud crack or pop to them when you got in the throttle. If you take the head pipe at the head and make it larger diameter and step it down several times this causes the pressure wave to speed up as it travels Down the pipe. This in turn helps draw the next pressure wave out of the head. In other words it helps the heads breath. If you take these stepped down head pipes and dump them into a larger canister it quickly slows the pressure wave down but allows the gasses to expand it acts like a silencer on a gun barrel. In essence it’s kind of the same thing just a lot less pressure. It you take that large can “your muffler” and put some kind of media inside of it. It will deaden down that sound even more due to the pressure waves getting all mixed up “the packing or louvers inside the muffler”. If you cut that media down to a minimum say short louvered baffles then add a reducer you now take those mixed pressure waves which is more like a large puff rather than a crack and speeds it back up as it exits the muffler. This is why it gives it that more of a thump sound because it’s now resonating inside the muffler can itself. The key is finding a mix of intake, cam, head pipe, and muffler that allows the largest pressure wave to form and still create that draw on the head as well as that slowing inside the muffler and that final draw as it exits the muffler. As each pressure wave enters the muffler it create another “shock wave” through the gasses inside the muffler and they act like ripples in water almost. Eventually it tuned properly it will have a very nice sound and perform very well. The two into one really helps the draw on the heads. The M8’s heads have a lot of potential for performance from the factory. So helping them breath in any way you can will only give you more power and better sound. The more air you have going in the more air you will have going out. You can get a rough idea of what kind of power out put a bike has “naturally aspirated” by the sound of the exhaust. It takes a while to learn what the different sounds mean, but the more you learn about it the more you will realize that you can pick things out just by the sound of the bike as they are idling through the parking lot or accelerating from a stop light.

[@HOLYSHIFT]

Sounds sick ! People should hear it personally !

[@jasonallen6406]

You are right. As good as it sounds in the videos, it really doesn't do it justice. He pulled out of the khromewerks booth in daytona and i was shocked at how much better it sounds in person. So was everyone that was trying to figure out wth bike was just running. Lol he definitely solidified my decision to go with the 475 cam too.

[@amphibdriver1]

The reason this two-into-one exhaust has such a pronounced rumble is that the muffler on this exhaust system is completely open and the outlet is only 1.5 inches. This really amplifies the exhaust sound and also boosts the low-end torque because of the high exhaust velocity.

[@robertm9848]

Exactly right

[@sammyalfaqih1491]

I’m keeping my bike 2 in to 2 I’m gonna tell Dave to do it and see how it sound 😉 I’ll definitely keep you posted 💪🏼

[@Jim_Berry]

You should do a ride video with all available baffles. Can you hear the radio with the reducer?

[@kevincarnes7598]

I remember that video! I think it sounds great on video so, in person must be even better! Dave put the other baffles in and sounded great as well.. he said with that one you may get more torque but, you decided on the reducer… I’d like to do a 2 into 1 like yours… I have the 107 as well with the S&S 465 cam kit.. pump/ plate… it would probably sound great too! Great video as always John!! Love your videos… always look for em as soon as I get on! Thanks for what you do!!

[@byoung8528]

I have had the 475 cam in my 107 for 2 years and thought it sounded and performed well with my decatted 2-1-2 head pipe and V&H slip ons until I installed the Khorme werks 2into1 outlaw with the reducer, Wow sound is amazing a little louder but not obnoxious and the torque moved right in to the sweet spot. I have had 2into1's on an EVO, twin cam and M8 and would never go back to 2into2. One caution when running the 475 cam with the factory head pipe is the bike tends to run richer with that cam and the clutch side pipe is lazy and does not expel the exhaust gases with the same velocity so at idle or in rally traffic the fumes drift up on your passenger and can be unbearable.

[@josedeltoro7453]

I got a 2 into 2 with star racing 30/30 cam, v&h power duals, khrome werks slip on with ripper baffle and power vision tune and its loud as hell. Your bike sounds amazing.

[@Sbhunter1]

John the sound from Mad Max is badass!!! Glad you put out the info on the reducer by Khrome Werks!😀👍🏽👍🏽You the Man, although Air Force!😜🤣🤣🤣👍🏽

[@anthonyb5614]

I have the 2-2 slip ons, I wonder what it would sound like if you put the reducer baffle in the right side and the left side louvered?

[@robertfagan8833]

Glad to see your back and had a great time down here.. thunder dome is a perfect name for that Busa.. that reducer in those pipes sound amazing.. nothing better than a amazing exaust sound

[@Joe_M_1109]

Hey John love the content! In your opinion is it the cam swap out (stage 2) that makes your bike able to stay on the higher rpm range and not sound like something is wrong. I’ve watched so many of your vids and I always see the RPMs so high on my 22 road glide with a stage 1 when I get the RPMS that high the motor sounds like it’s straining. If you have a chance to see this would love any knowledge you can drop! Thanks for everything brother.

[@Todd-e6g]

Mad max sounds awsome I have 114 with torque cam v h power duals with krome works ordered reducers did little for my setup tried louvered and ripper incerts with the reducer both but dyno very well the rippers with reducers gave me the sound and performance I was looking for .great channel thanks.

[@amberbali8881]

John, I have asked you about this before but don't recall getting an answer. There are three inserts (baffles) available, Performance (has an adjustable tongue inside, bottom right in the picture of all inserts ), Louvered (top right in the picture of all inserts) and Ripper (straight through and is loudest but poorest performing of the 3. It's the middle picture of all inserts). Can you tell me for certain which one of those you are running? I believe it's the Louvered as I can't see the tongue of the performance baffle and don't think Dave would even consider the Ripper. If you don't know, can you confirm with Dave? I run the 2 into 2 Dominator KW exhaust with the tongued performance inserts on my 21 RGS , Stage 2. Works great but I'm switching to a 2 into 1 KW as I now have regular bags and want the performance look. I have been a 2 into 1 advocate forever (2-1 wasn't available last year (sold out/back order) when I was doing the build last year). I will then contact KW for a reducer (although it looks like the items on the top left and bottom left in the picture of the inserts. I don't think KW will sell to the public. I will have to get a part number from them. Thanks for any definitive info.

[@CYCLEFANATIX]

Like I said in the video, the one I have is not in the pictures it’s called a reducer. You have to call Khrome Werks and ask for it.

[@amberbali8881]

@@CYCLEFANATIX Just watched the original video of your first start with your pipe. I now see what the reducer is.

[@morriscovington732]

I'm glad you choose Thunderdome for the Busa...it made my day and it fits...MaddMax and the Thunderdome...thanks John for picking Thunderdome...and the sound of MaddMax is second to non...great video 😊

[@CYCLEFANATIX]

Yes it was you now I remember Thanks

[@chadkirby5438]

I think they finally did put that baffle on their website….it looks to be the Ripper insert….brings the diameter dwn to 2.25 in… I’m def getting that set up for my RG for sure!! Sounds amazing!!🙌🏼🙌🏼

[@GPA7]

Ordered my 2 into 2’s from Jared at KW. They are different than the Rippers. Also they don’t supply the bolts. You have to purchase the 1/4 20 x 1/2” separately.

[@B702K]

Gotta agree. Sounds incredible!

[@btoso32]

Life hack for everyone. If you run a reducer, dont have dog/cat food in your garage over the winter. I had mice pack dog food in my exhaust up to the headers haha.

[@jesseting3599]

Do you mind a sound clip for listening? Thank you~

[@russellhalleran9080]

Great info! Sounds Awesome on your videos! Ride Safe Brother!🇺🇸🇺🇸👍🏻

[@J3B24]

Honestly, I could listen to your bike like I am listening to my favorite song. It is one bad ass sounding Harely.

[@BigObikes]

Hey Jon love your videos I have 2 into 2 khrome werks dominator full exhaust on my 2019 road glide 114 with s&s 475 cam and I’m gonna take the louvered inserts out and just nip the welds off where the flange attaches turn them around bolt them back on there’s your reducers for the 2 into 2 hp plus mufflers I let you know how it turns out haven’t had it on the dyno yet will let you know how it works out up here in Ontario Canada cheers

[@michaelallen9784]

Thanks for letting me know that I had to "call" khrome werks for a set of reducers! I had no idea. I couldn't find them anywhere, after watching your exhaust install video!! Ordered them today!! Thank you brother! Can't wait to hear the difference! Oh by the way, I let them know that you are responsible!!

[@CYCLEFANATIX]

Anytime Michael thanks for your support brother

[@abdulmateen19]

Just ordered mine today for my slip ons. Have the louvered baffles now and they work really good on my 131. May change to their 2:1 with the ghost pipe once I get my cam changed out

[@jeffelliott7024]

Always like your videos, but this one if your going to explain the exhaust, fire it up and let make the noise. Have a good one, cant wait for next video.

[@xpresident]

I agree! That’s one mean sounding whip you’re riding brotha!

[@socal310HD]

what was the difference in sound from it with no baffle to it with the reducer in? ive heard it on your video but cant really tell the difference, does the reducer make it deeper? louder? or is it deeper tone without it?

[@CYCLEFANATIX]

Yes, he seems to make it deeper and Rumble more

[@patrickfoley9256]

John, how did your front fork seals work out? Remember you replaced them before your trip. Glad you made home safe.

[@danbarrette9888]

Nice to see the terriers in the frozen four. Hope to hear that amazing exhaust in person on the 29th.

[@jasonbreedlove495]

The s&s 475 or the zippers 468 is what I'm putting into my 21 RKS. Love the tone of them with any pipe, with the 475 sounding so damn nice. So what cans you putting on the busa?

[@kellybgliding]

Mad Max Sounds really good 👍🏾

[@tsnsh]

Hey John, appreciate all the information. Another name suggestion for the Busa. How about Elvira? Thunderdome is great, but the Busa may just be too sexy.

[@clubstyleridahd4695]

The reducer gives a lot of low end power. I have the s&s superstreet with the same style reducer. When I took it out it had no low end power at all. Also made the bike shake more with out it

[@h3r63rt]

Aren’t you a bit couriers what the 3rd one would sound like? Did you get more low end torque with that reducer?

[@CYCLEFANATIX]

Lol not really but now you got me curious lol

[@shidoshii1474]

Thanks for the info.

[@PatrickElleman-nd4zv]

How did the black chrome on silver back hold up? Would you use those again?

[@CYCLEFANATIX]

Definitely 👍

[@glennwoods7829]

Thinking about using JD cycle to build my motor anything do I need to know about Dave. Thanks Glenn

[@CYCLEFANATIX]

Great guy and great shop fully recommend

[@glennwoods7829]

Waiting to hear back from Dave on a quote

[@natedogg333_]

Loud is good but how loud is too loud? There comes a point when you sacrifice your long term hearing for loud pipes. Do you ever notice after a long ride any ringing in the ears or headaches?

[@CYCLEFANATIX]

It’s not that it’s too loud. It just sounds great.

[@owdiss1978]

I have stock gutted head pipe on 2022 ultra limited with khrome works slip ons and ripper baffles also ss 475 cam I got 120 hp 132 torque and sounds really good

[@snakebite6511]

Exhaust is very personal, what sounds awesome to 1 person is not appealing to another, personally i hate the sound of 2 into 1 I prefer the sound of 2 into 2 true duals

[@gregoryhousch725]

Could The Reducers Be Used With KW Slip Ons?

[@CYCLEFANATIX]

Yes

[@geraldgoodiii6993]

It’s their zombie baffle pretty much yes ?

[@billprusow1654]

I'm calling them tomorrow to order.

[@jameshefferman6492]

What baffle did the pipe come with?

[@CYCLEFANATIX]

Louvered baffle

[@RidersUnited]

You actually probably gain horsepower due to a bit more back pressure. I did same thing on VH pipes in the past. Fuel Moto was impressed with results during tuning comparing to VH without it

[@michaelwynn6969]

I got the two into two. I’ll look into that. Thanks for the info.

[@HDFXSB645]

And?

[@savagebeardsmen6842]

Love the sport too I got a RGst 117 but want to get a R6 aswell

[@bryanwalker3110]

Sounds amazing, does ANYONE have this exhaust setup on a 103 twin cam? I’ve searched KZbin and can’t find a video of it

[@brandonmartin506]

I may check on it I have the Louvered in a 2 on 2 now

[@shoey5406]

I was told if i took my reducers out i would lose up to 19 foot pounds of torque, i left them in

[@PaulBerry-bm6lk]

Good video

[@brettcreech3490]

Love the sound but I like the looks of the 2 in to 2 better the 2 in to 1 looks like something is missing. Just me love the videos brother glad you made it back safe.😎 God bless.

[@FLYANDRIDE15]

So that’s the trick!!!! 😮😅

[@victorgonza4528]

JD cycle custom dent on the muffler, gives it that deep bark

[@CYCLEFANATIX]

Haha yeah that to 👍👍🤣

[@kcrady72]

I wasn’t a sub when Silverback found a new home. With that being said, it’s going to be a sad day when Mad Max leaves the building. We all know it’s coming with the bad ass 24’s out.

[@thunderglide]

I tried to get this exhaust but nowhere to be found. I contacted chrome works directly but don't sell direct. Told me to order from drag specialties but I can't cause they're out of stock till sometime in May but bike is being built now

[@mattreed8618]

202716p is the part number for the reducer cone.

I have the 2 into 1 outlaw exhaust and I have the reducer installed and it doesn’t sound the same. There is a packing type baffle in the exhaust that came from khrome werks do i remove the packing or baffle that’s in there ? Thanks for the great videos. Bike is bad ass.

Should’ve named the Busa Toe Cutter 🤷🏾‍♂️
