- This video is about how to modify your Harley stock and aftermarket exhaust pipes to increase lowdown and midrange torque. These lollipops will reduce gas reversion therefore you get more torque and horsepower.
“ at 3.13 I meant nuts not washers :)
Seriously the gutted stock slip-ons with lollipops sound absolutely amazing. Very nice loud throaty deep rumble. You can’t hear it properly in the video. Massive difference in the flesh!

We used to weld a big washer on the end of a bolt and attach it exactly like this one. Then you can rotate the washer, to close or open up the exhaust. Worked perfect to tune dragpipes. Turn it 90 degrees and you have full blown dragpipes, turn it back and it would give you backpressure and less noise. And anything in between.
Too late 15 years ago I bought rush slip-on . I still have the originals. This rush have worked ok . Not loud but when you twisted the throttle it will bark👍🏼
Thank you so much for your wisdom! I recently drilled out the baffles on my Screaming Eagle 2’s and had major decel pop. I put two of these in my pipes and the pop went right away and I noticed it added torque! Thank you for sharing God bless you!
Thank you for sharing your experience. I’m glad it worked! I also got my Screaming Eagle 1’s on right now, with the lollipops in there. It does work really well, especially with a nicely tuned carburetor. All the best!
Just get a long steel drift and a hammer and knock out the center plug of the baffle. This will leave the baffle in and will allow for the exhaust to flow straight out giving a nice sound and better performance.
Could you tell me how you did this please?
I bought a "performance tuned" Harley Davidson Centennial Edition Softail Standard in Vivid Black. It's beautiful! The best thing the previous owner did on my Harley Davidson, was to save the factory parts he had removed when he had it tuned. When I bought it, it had a Vance and Hines short pipes setup, installed with no baffles. It was extremely loud. It also has a larger than stock aftermarket carburetor and aftermarket ignition module that has been tuned to maximize power. It was very loud when I brought it home, and made popping sounds on deceleration that sounded like gun-shots. It was pretty much unrideable. The throttle response was snappy to an extreme. The previous owner paid good money for the tuneup. He wanted it that way, but in the end didn't ride it. I bought it, and I hated it. Mostly the loud popping sound it made when I let off the throttle was simply too much. So, I re-installed the V&H baffles that were unused in the box of goodies he gave me with the purchase. Thank you, Previous Owner! That was better, but it was still too loud and still popped some. So, finally, I put back on the nearly new factory pipes with baffles. Now it sounds better! And, there is no more popping on deceleration. It turns out, I like the factory sound! Next, I'm going to see if I can re-install the factory carburetor and air cleaner. The aftermarket one works, but the gas mileage is an unimpressive 37 MPG in mixed riding. The ram-air design air-cleaner is too large. It forces my right knee to stick out into the wind, so my foot tries to blow off the peg at speed. I think Harley Davidson factory balanced everything out pretty well with the original design.
Congratulations on your new bike! Yes, you’re right. It was designed perfectly in the factory. You don’t want too many crazy modifications else it just gets worse in every respect. Factory carb is excellent. Only a few tweaks and it works well with even louder pipes.
I put a 1/4" thumb screw in my 1-3/4" drag pipes. It is enough to increase the low end torque a lot, without sacrificing the sound of the pipes. It just lowers the tone a bit, and takes out the reversion.
We used to use freeze plugs. You drill a bunch of small holes in them then tap them into the end of the exhaust. I think we tanged the edge of the freeze plug a bit to make it bite into the pipe as it went in. State Troopers in Texas were hard on us loud exhaust guys. Good video Aron!
Thanks. Very creative! Never heard of that before. Luckily here in the UK police is pretty lenient, they leave cruisers alone, so I usually swap them back with the screaming when I want real bark.
Thanks for sharing, great design, the washers can be changed out to different sizes without having to disassemble each time. I just went and did this to my 2004 Harley Roadking with tc88 with 3.5 Rinehart true duals, SE breather and 211 cam. I used the 1.5 washer in the baffels about 2 inches in. The sound after install is deeper and the bike seems to be more hard hitting. As soon as it quits raining ill update.
Great stuff! I also put them in my screaming eagle pipes too, and the bike is running better and virtually no popping..Looking forward to the update

Ok, there is quite an improvement in overall torque. Low,mid, and picked up the high end some too. I really like the deeper rumble but not as loud.I can feel the difference. Really impressed, thank you so much!!!
You’re welcome! I’m glad it worked!
Either jet your carb or get a S&S carburetor or S&C(,Screaming eagle) carburetor but still might have to jet it either way you are creating less back presure
What year and model of Harley is this? What do you prefer?
Question on my 2021 Harley Davison Triglide ultra classic trike don’t will affect any thing if I do the same as you do on your bike. Thanks for the video 👍👍👍
I’m not really sure about yours being a new model. I don’t know if you can take out the baffles that easy. Plus you got the catalytic converters in there. These mods work best on these older pipes with no CAT in them. But if you do manage to do it, I’m not sure how it affects your bike since yours is an injection model. Mine and all pre 2007 are carbs and we tune them quite easily once exhaust has been opened up.
great video, thanks! do you have one for your screaming eagles with the washer?
Thanks! In my screaming eagle I put the same size lollipops a bit further in the pipe where it holds the baffle. Works great!
nice one! my question is, was there any fiberwraps around that perforated tube?
Hi Henri, No, there wasn’t.
So I have a soft tail standard and want to have loud pipes. After all I need people to hear the bike coming from afar to stay more alert 🚨 of the impending hazard we can cause if you’re not paying attention. I’m not persuaded to follow the noise pollution laws as my life is well above someone else’s sensitive hearing. With thy said. Will I need to make smaller lollipops for my pipes?
Even if you make the lollipops smaller it won’t make it much louder. You won’t even notice it. That lollipop size will give you the best performance with this exhaust. These modified pipes will give you a pleasant rumble that is louder than stock, especially when you are accelerating. At idle or low steady speed though, it’s quite soft. If you want something substantial, I would go for screaming eagle or vance & hines. I use these ones in the video around MOT, and it’s ideal to use them on long trips/ tours, but then I usually end up putting my screaming eagle back on for more bark. I like both to be honest so keep swapping them lol
I used this exact set up for my screamin eagle pipes. Decel pop just as bad and no change in torque/hp. It was worth a shot though
Bit different with the screaming eagle. I got my screaming on currently. I put the lollipops further in the pipe where the baffle is secured. ( used the same hole) and with the carb set up properly, I get no decel pops at all. Your carb might be set too lean or too rich
@@aronsgarage834 my baffles are pretty deep in the pipes. I guess I'm limited to how far I can get a wrench down the pipe to tighten the lollipop but ill give it a shot
I had one of my exhaust baffles fall out from slip on because of rivet failure. Finding baffle crushed after turning around an locating. My slipons are screaming eagle stamped closed current an too loud for my cop neighbor already so instead of pulling other baffle I repaired an replaced worthless revit with stainless. Now it's better than original side, so I fixed it with stainless too! Did you coat or paint your pipes? I love the color!
Good job, Tim. I got my screaming eagle back on! I always miss the loud rumble when I have my modified stock on. My baffles are fixed with 6mm bolts. No, I didn’t paint them. All stock stainless
Hey nice invention good sir! I've recently gotten my first bike being a 2005 Yamaha xv250 Virago and have seem tons of videos of people drilling g out their baffles with the hole saw, but a few others where they would simply drill 4 holes into the metal around the baffles too. I haven't drilled the whole baffle out yet though due to a few people saying it would mess up the "back flow" and thus would need to "rejet" their bike? Not totally sure what all that is yet so I just drilled the 4 holes hoping it would still retain some pressure for the "back flow/pressure. However Itz not the same sound I want as it is by just taking the whole baffle out.
My question to you is: would this lollipop idea remedy the whole back flow/pressure problem for me or would I still have to "rejet" my bike or carb or whatever it is, cuz I know that's not a cheap fix from what I understand which I can not afford at this time.
And would I use the same size or go bigger/smaller?
Thank you for sharing and i hope to hear back from you!
Take care
Hi Ian, It would definitely remedy the reversion/back flow problem but you will also have to adjust the pilot/mixture screw to make it richer. Not sure about re-jetting. It may need that too because it’s a small engine. I think it’s best to do more research on this. Cheers,, Aron
@@aronsgarage834 thank you for replying!
And cool sound good, I think my bike is running a bit lean cuz I looked at the spark plugs and there's no gunk or anything really at all on them. Idk if you would know If this is a problem or not, but is it normal for when I start my bike, I said the joke all the way to the left and it revs really high and gets the bike started in everythingBut when I move it over 3/4 to the right it idles super slow then if I push it all the way to the right the rest of the way, it picks up again to I guess normal idle speed? Is it supposed to speed up again after it slows way down 3/4 the way to the right? I tried letting it idle at 3/4 the way where the idle is super deep and low/ slow last night but I think it like flooded the engine due to being too lean? Cuz the bike wouldn't start again till this morning and even now it's still having weird throttle response. Can this be fixed by adjusting the air/fuel mixture or the carb idle speed? Or adjust the other engine idle speed on the other (left)side of the bike?
Thanks for the help and very much appreciated any advice or tips!!
Also idk if this is any indicator of the bike running to lean but when I'm starting or idling the bike I smell gasoline quite a lot and can't remember what I read that being an indicator for. Thanks!
@@iangroover1188 if you smell gas, it’s running rich. To start with, I would highly recommend taking off the carb, taking it apart and giving it a good clean. Especially the slow circuit. Then see where your pilot screw is at and adjust once assembled.

How are the foot peg, handle bar, and seat vibrations when you go over 55-60 mph?
Very pleasant at any speed. I usually ride at around 65-70 on highway with no problems.
@@aronsgarage834 What year is your bike?
@@dry509 1999 Super Glide
Is there some kind of formula for getting the right size washer? I have aftermarket slip-ons not sure if I have the same diameter or not.
Don’t have a formula, I kist experimented with all different sizes. You’re bound to have roughly the same diameter exhaust, so the washer I used should work well in yours, too.
How much space do you want between the washer and inside of the pipe?
Around 7mm as I measured.
Thanks for the vid. How long is the rod for the lollipop I don't know where to cut the rod.
Mine measures 40mm in my stock pipes. Not sure about the ones in my screaming eagle but definitely longer because the inside diameter is larger too. Hope it helps.
Stay off the tools man! If you can't work that out😅
Do you need to put it at end? I am considering adding the lollipops before the cone where the baffle exists
It doesn’t have to be at the end. I also installed it in my screaming eagle where the baffle is secured with a screw.
Hey Aron how did you come up with the distance from the end of the muffler?
In the stock pipes, that was just the distance that allowed me to stick the lollipops in. You don’t have a lot of options as the stock exhaust is smaller in diameter inside..
@@aronsgarage834 Thanks
Why would anybody want to wreck those nice stock mufflers? They sound great just as they are.
I'm thinking of getting an 883 Superlow for tooling around town. Do you know of anyone who did this procedure on an 883, and if so, how did it sound?
Yeah I do. One of my friends had it. Sounded great, pretty much the same as on the Dyna.
My only problem is that idle is really quiet, so I’ve since gone back to my Screaming Eagle with lollipops installed of course. But if I was to go on a long trip/touring, I’d put them back on.
@@aronsgarage834 Thanks for the reply.
Can I order 2 of these from you please?? I’ll pay whatever man. I need these any have no way to make them.
Depends on your exhaust. Are you looking to put these in gutted stock pipes? Or other open exhaust?
Whats the internal diameter of the pipes that suits 35mm lollipop??thanks
The stock I’m showing in the video is 51mm and I also have it in my screaming eagle which is 57mm, and the 35mm lollipop is perfect for both.
@@aronsgarage834 thanks..😀
@@banayadryed most welcome! Hope it helps. 😀
@@aronsgarage834 I'm gonna apply it to may Yamaha Big Single SR400, I have change the stock quiet muffler, and since then deceleration pops is more obvious.so I hope that will help to cancel most of the decel pops.
@@banayadryed it will get rid of most of your decel popping. I have pretty much zero popping on my Harley. Of course the mixture screw needs to be adjusted as well to give it more fuel at idle and slow circuit.
