In my 2019 Sportster 48 Special, there where cats inside the mufflers before the baffles. I didn't cut out the baffles as in the video, I just ran a cup saw on an extension thru the muffler. Wham Bam thank you Mam. sound Great!
@flatroc1 nice idea! I wana do the same for my 2020 sportster 48. I want to also use an extender with a 1 inch drill saw and make a hole in the baffle. Question bro .... did u lose back pressure or lose any performance with this easy/cheap mod? Have you had any issues in the 1 year or you would recommend this for others? Thanks a mil !
Hi Chadd, thanks for the help! You have fun riding and fixing up your machines! I am currently overseas ... will be back to Minnesota/ Wisconsin next summer. Take care! Peter M.
I found this video over the Memorial day weekend. Thank you. My 2011 Harley Superlow sounds so good. Thank You. I will make a video. Called loud pipes. You saved me 700 bucks. here in Bama.
Hi Chadd, thank you so very much for your great advice! You are a gentleman ~ sharing all these with others online. Wish I could buy you a case of beer or something. I guess we will go ahead ~ drill it (1 3/4") and pull out the baffle and see if there is that catalytics converter inside. And then start it to see how she runs. The worst will be we will have to put the damn thing back inside the pipe and secure it. Thanks much! Peter M.
Hey man, I'm stationed at Bliss and had been trying to figure out how to remove the baffles from my Victory Cross Country 8 ball. Thanks for the demo. 14K,
I believe your baffles are either riveted or screwed in place, look behind or on the bike side of your pipes and look for rivets or screws. These will be whats holding them in place. If not, then I'm lost
Did this to my Night Train with a 1-3/4" hole saw. Worked great, took 20 minutes start to finish and left the exhuast fully mounted. Sounds nice and deep now, but still not obnoxiously loud.
Yeeesssss, it has such a beasty sound now. No problems with any backfire or pressure loss. Everything is good and the Exhaust roars when i start it up. Thanks for the video and help :D
Very helpful. I mean you don’t have to put those factory exhausts backs on it. It sounds super super loud and so satisfying.hope you have good neighbors lol
I just banged out the baffles on my 06' 883XL, Improved sound quality, no noticed loss in mileage. I drove an additional 8 miles over the expected 100mile stop for gas.
Sounds good, I have a 2014 Sportster "48". I went with the Vance and Hines short shot staggered in black. I added the quiet baffles because the stock V&H were pretty loud.
@ Steven, YES IT MAKES A HUGE DIFFERENCE! The Dyna's have a catalytic converter built into the slip ons...I have tried to NO AVAIL to get them out. Sorry bro.
So I decides to try the poke/drill a hole thing first to see if the effect was loud enough. There were already holes in the metal plate on the baffle. I went to widen it and the welds on that plate broke. The plate fell right out. It sounds way louder and pretty awesome. The baffled are still welded in. Since that plate is the same circumference as the baffle, would make a difference to remove it?
Ah the dremel, one of my most used tools. I prefer baffled, I have an ironhead I had to shove 8 inch baffles in and it didn't change the sound at all but a nice boost to midrange. Guess I should look into some slip ons like those.
Hi Chadd, thanks for the quick reply! You're the best. If you could please spare me for a few more questions. Will the baffle come out as "easily" as the one me and my friends took out on my other 2005 883? I understand there is some catalyst thingy attached to the new pipe, CORRECT? will that make a difference, more difficult? So, we will have to "remap" this new 2013, correct? Or can we try running it first or will it hurt the engine as it runs much leaner? Thanks so much ! Peter M
Hi Chadd, thank you very much for your video and information! Very helpful! I have a 2013 883 Low. Can I simply drill the baffle OUT (I did this to my other 2005 883) be done ? Thanks! Peter M.
Thanks a lot for this vid, brother. I recently bought an '05 883R (black) with 4g on the mileage, mint, for 3k. I HATE the sound compared to my old '72shovel night train custom so the baffles are coming out, I'm throwing some shorter rear shocks on, breezer bars and maybe a different air intake. Your thoughts on a good performance, non cumbersome, air setup?
i have a 2004 883 carbed i got a extra set of factory pipes to see how it would sound and not to bad quite happy its loud thats for sure and wont do any harm eventually ill put on hookah headers but for now thanks guys i like it alot.
Hi, I’m Roberto, I read in a many forums that it is recomended to remap te motorcycle, my question is, what happens with de retention of gases?, the spark plug is very burned ( tip black)? And they sound the same as the vance and hines? And if I don’t remap mi motorcycle you think what I’ll have a problem?? Regards!!
i wanted to do the same shit ... as i like the look of the stock pipes ! Have u inserted something after removing the baffles !! Howz the performance ? any issues in pick up? is it torquey enough ? What about the fuel consumption ? FINALLY IS THE SOUND BASSY ENOUGH ?
Well mapping is when the dealer or a certified mechanic hooks the bikes computer up to a device that changes the fuel/air mixture (mapping) for optimum performance. usually costs about $150. Personally i don't think it is needed unless you have an aftermarket air filter as well.
Interesting. I took off my pipes on my 1991 Sportster 1200 and the baffles are only fastened with a bolt so it's super easy too take em out. However I need to get a different air filter and also find out if I need to re jet the carb.
I like the way the Iron looks, but I could not live with the 883. I love the longer stroke of the 1200, it really runs at a nice low rpm at highway speed.
Literally about to do this but before I do it can you please tell me if there's any performance issues or things I have to do to the computer I don't wanna mess the bike lol
I just punched the bottom out of both of my baffles and it sounds great and gained performance. I have more low and mid range torque. The RPM range is wider as well. I have no complaints at all. My bike is a 2011 Sportster XL 1200 Custom.
I have a 2012 sportster xl1200 custom and got slip-ons and the Harley shop told me I was fine but if I were to straight pipe it /remove the baffles I would need a fuel programmer. Because it will burn the valves. I now have a heavy breather with rush slip-ons and a screaming eagle race programmer and gained 20hp 15ftlb torque and about 10 mpg. I would recommend the programmer if you don't want to put unnecessary money into your engine. Ps fuel injected need back pressure to run correctly
Great work guys. What a difference in sound! Just wondering since we make license plate backers if that extended backer you have is for a military sticker?
The issue with both burnt valves and low end torque is that, because the exhaust has better flow, the engine is now getting more air. If they have this, along with other mods, they could be running too lean causing both of those issues.
I dont this on my 2018 883 and couldn't get baffle out.....ran into about 2 inches of steel mesh in the top of the pipe...do you know if they changed the exhaust on a 2018....or is there something else I need to do to get baffle out?
I bought a 2018 sportster 1200 iron can I do same willl I need to tune or will I just get less gas mileage not worried about the mileage just thought I asked b4 I start wrenching on it
Marisol Macias I think the newer ones have the catalytic converter in the slip on itself you might want to check if it is they're pretty hard to get out and you might just want to purchase some regular slip-ons
I have a 2009 HD XL Sportster Low (stock) and would like to do the same, Besides removing the baffles should anything else be done before I start riding, And mapping How can I get it done, What is it , Sorry newbee!!!
hopefully someone can help me, i have a 2012 sportster 1200 custom, i have a set of vance and hines straight shot slip ons, but no mounting brackets ( they were given to me) where can i find the bracket??
great video, thanks... Just did this on my 2016 Iron 883. - had to do differently because of the taper of the pipe, the inside baffles matched the taper, so we had to cut off the pipe at the big part before the taper at the back... sounds AMAZING... but.... I am super concerned about it running too lean, has the stock air cleaner, but was advised not to ride it like this as it'll lean it out and make it run way hot and burn it up.... do you have any insight or thoughts on this?
fix the fuel to air ratio by jetting if carbureted (I'm not familiar with Harley fuel delivery) or get over ℅ injectors if fuel injected. only way to fix that problem.
+Bill Larkin you can get a fuel controller at any of the aftermaket places. They go from simple plug and play, to you can change the fuel map in 100 rpm increments. That is the best way to do it. Newer EFI Harleys come from the factory way lean to begin with due to EPA BS, so it's best to get a fuel controller anyways.
+gostrydr thanks! - ahhh the EPA crap, I was wondering WHY they were like that. got it. - I just bought the V&H FuelPak FP3, that should solve the problem? :)
Hey Chad, I have a buddy with the 100th aniversary edition 883, he doesn't have the $ for all the aftermarket stuff but HATES how quiet the bike is. Its his first and he wants that sound. Any effects of performance or longterm damage concerns before we do this? P.S. thank you to you and all the others who serve.
Well, here's the skinny... It will sound better after doing this...you will lose a little low end torque. And she might pop a few times here and there. But "eventually" he will want to pay the $150 and get the engine "mapped" (they adjust the fuel/air mixture) Taking the baffles out like in this video will make the engine run hotter (but not too much) I ran mine like this for 2 years with no issues.
I drilled 3/4 inch holes in the baffle on my 04 sportster 1200 instead of removing the whole baffle. It sounds pretty good! I made a video with the sound so you can hear it.
Well it seems that the new harleys have a catalytic converter in the slip ons...I bought a new street bob recently and because of the converter cutting out the baffles is no longer an option. If you were to possibly get an electricians auger bit and just went to town boring the hell out of them, it might work. But this video was on a 2011 iron.
I just bough a new HD sportster 48, 2017 model. I want to remove the baffles from the stock pipes. Does anyone knows and help me if this action will create any problems to my HD. Do i need to do anything else after removing the baffles or would the removal be enough. Thanks
You should get the computer remapped. But a '17 probably has the cats in the slip ons, which is very hard to get out. I would recommend a set of cheap slip ons instead. You can install some torque cones if you don't want to re map.
You would have to look into the slip ons, but most models past 2012 have the cats inside the slip ons, I hear you can get them out at great effort, and heard it's just better to buy a slip on with no cat.
I have a 2009 1200 sportster, I want more noise, trying to figure out getting rid of the baffles, I’ve heard that hurts your low-end torque, and can mess up your pistons, you have to adjust the fuel flow?
+Hector Delgado it should, but you will want a fuel controller because it will run lean. Newer Harleys cone from the factory really lean due to EPA BS anyways.
“ use the rag to hold the pipe” * throws the rag on the floor and proceeds to cut lmao 🤣 I love it.
Your taste in music is very much appreciated xD
16000rpm true
In my 2019 Sportster 48 Special, there where cats inside the mufflers before the baffles. I didn't cut out the baffles as in the video, I just ran a cup saw on an extension thru the muffler. Wham Bam thank you Mam. sound Great!
@flatroc1 nice idea! I wana do the same for my 2020 sportster 48. I want to also use an extender with a 1 inch drill saw and make a hole in the baffle. Question bro .... did u lose back pressure or lose any performance with this easy/cheap mod? Have you had any issues in the 1 year or you would recommend this for others? Thanks a mil !
@@abdulkhawaja9792 It all worked great and sounds beefier too.
That sounds really good! I have an Iron 1200. With this tutorial I now know how to remove the baffles. Thanks for the vid
Hi Chadd, thanks for the help! You have fun riding and fixing up your machines! I am currently overseas ... will be back to Minnesota/ Wisconsin next summer. Take care! Peter M.
I found this video over the Memorial day weekend. Thank you. My 2011 Harley Superlow sounds so good. Thank You. I will make a video. Called loud pipes. You saved me 700 bucks. here in Bama.
ROLL TIDE!! I do accept tips! hahaha
Hi Chadd, thank you so very much for your great advice! You are a gentleman ~ sharing all these with others online. Wish I could buy you a case of beer or something.

this is the best way to do this and the first mod I do to every bike I build.Respect!
Michigan love brother. Got myself same bike love it, just ordered some exhaust pipes, fuel pak, and air filter cant wait to make it sound good..
Hey man, I'm stationed at Bliss and had been trying to figure out how to remove the baffles from my Victory Cross Country 8 ball. Thanks for the demo.
14K,
I believe your baffles are either riveted or screwed in place, look behind or on the bike side of your pipes and look for rivets or screws. These will be whats holding them in place. If not, then I'm lost
Thanks, I'll do that as soon as I get back.
Did this to my Night Train with a 1-3/4" hole saw. Worked great, took 20 minutes start to finish and left the exhuast fully mounted. Sounds nice and deep now, but still not obnoxiously loud.
Very cool! Loud bikes saves lives! Thanks.
Yeeesssss, it has such a beasty sound now. No problems with any backfire or pressure loss. Everything is good and the Exhaust roars when i start it up. Thanks for the video and help :D
it is loud as hell! with a nice deep rumble. a re map from the dealer is always a good idea
Great video guys. I appreciate it. I know exactly what to do now. Thanks again.
You have made my day with this video thank you so darn much for this video
Very helpful. I mean you don’t have to put those factory exhausts backs on it. It sounds super super loud and so satisfying.hope you have good neighbors lol
I lived in El Paso Texas for a bit when I was in the ARMY, loved it there
Nice soundtrack for the job, man! Also, the exhausts sounds really awesome!
Miss my Michigan plate!!!
But enjoying the Florida riding!
Will be doing this soon until I can afford pipes!
I just banged out the baffles on my 06' 883XL, Improved sound quality, no noticed loss in mileage. I drove an additional 8 miles over the expected 100mile stop for gas.
Sounds good, I have a 2014 Sportster "48". I went with the Vance and Hines short shot staggered in black. I added the quiet baffles because the stock V&H were pretty loud.
the dremel tool worked perfect, good work...
Cool info and good taste in music!
@ Steven, YES IT MAKES A HUGE DIFFERENCE! The Dyna's have a catalytic converter built into the slip ons...I have tried to NO AVAIL to get them out. Sorry bro.
nice shop guys, nice sound !
The soundtrack is outstanding!
Thanks from over in Fort Polk, vid was pretty helpful!
i think pipes alone is not enough to make a re map needed. but if you do the pipes and an aftermarket aircleaner...then yes
2" hole saw for sure. Just did my wife's 883 without removing anything. Like 15 min. Not as loud as I thought, but still cool as hell!
Erik Anderson what year bike is ur wife?
So I decides to try the poke/drill a hole thing first to see if the effect was loud enough. There were already holes in the metal plate on the baffle.

Since that plate is the same circumference as the baffle, would make a difference to remove it?
Holy shit that a big difference. Thanks for the video
Did doi g this project loosen up the packi g at all? Or is it nice a d secure after removing the baffle
Ah the dremel, one of my most used tools. I prefer baffled, I have an ironhead I had to shove 8 inch baffles in and it didn't change the sound at all but a nice boost to midrange. Guess I should look into some slip ons like those.
hey man ! really awesome video !! please make more !
Sounds good, I took the baffles out of my sportster with a bi metal hole saw and cordless drill efi can compensate like 10%
Without leaning out
I have 2014 Dyna Street Bob. Is there any difference as far as the removal of the baffle goes?
Anyone know if this same procedure can be done to a 1985 roadster ? Thanks in advance fellas .
Hi Chadd, thanks for the quick reply! You're the best. If you could please spare me for a few more questions.

Awesome mod man! I want to do the same to my stock 72.
do you mean the catalytic? mine seems to be bonded to the sides somehow
how did you get the bottom glass pack to slip off I cant get mine off
When you started the bike did you get any check engine light or any power loss on the ride? Please elaborate on the after math of the mod
very nice rumble...good work guys
Can I do this on a 2018 softtail deluxe?
will this make the bike run lean ?
Hi Chadd, thank you very much for your video and information! Very helpful! I have a 2013 883 Low. Can I simply drill the baffle OUT (I did this to my other 2005 883) be done ? Thanks! Peter M.

This may have been answered but do you have to tune it after ?
Hi, I’m Roberto,
I read in a many forums that it is recomended to remap te motorcycle, my question is, what happens with de retention of gases?, the spark plug is very burned ( tip black)?
And they sound the same as the vance and hines? And if I don’t remap mi motorcycle you think what I’ll have a problem??
Regards!!
i wanted to do the same shit ... as i like the look of the stock pipes !
Have u inserted something after removing the baffles !!
Howz the performance ? any issues in pick up? is it torquey enough ?
What about the fuel consumption ?
FINALLY IS THE SOUND BASSY ENOUGH ?
Will it mess up the compression in your engine?
So you just leave all the fiberglass in there? Do you gain or lose anything by doing that?
Do I need to get bike retuned if fuel injection??
would that be the same as cutting out the baffles from a 2007 HD 1200 sportster? does it have the same size width in the exhaust
i have a 2013 iron can ic ut the baffles out without damaging any thing on the motor ?
Well mapping is when the dealer or a certified mechanic hooks the bikes computer up to a device that changes the fuel/air mixture (mapping) for optimum performance. usually costs about $150. Personally i don't think it is needed unless you have an aftermarket air filter as well.
You just perfected this bike
i have a 2012 1200 c do i need calibration after i do this ?
Awesome thanks for your time showing this.
No problem 👍
I did it on an 2007 sportster custom and had no problems with riding afterwards. no check engine light or any power loss.
Interesting. I took off my pipes on my 1991 Sportster 1200 and the baffles are only fastened with a bolt so it's super easy too take em out. However I need to get a different air filter and also find out if I need to re jet the carb.
I was going to say, they fell out of my '95 883 stock pipes. I used to have to hit them with a mallet and push them back in all the time.
I like the way the Iron looks, but I could not live with the 883. I love the longer stroke of the 1200, it really runs at a nice low rpm at highway speed.
1200 upgrade kit ;)
the 1200 is a rocket!
1200 has a longer stroke?
The stroke on the 1200 and 883 are identical the only difference is bore size
I'm so glad I went with the 1200 over the 883
can i do this on street bob 2017?
Literally about to do this but before I do it can you please tell me if there's any performance issues or things I have to do to the computer I don't wanna mess the bike lol
Sounds great 👍
Did you install any torque cones? If not did you lose low and mid range torque. I'm all for increased sound, but not at the expense of performance.
I just punched the bottom out of both of my baffles and it sounds great and gained performance. I have more low and mid range torque. The RPM range is wider as well. I have no complaints at all. My bike is a 2011 Sportster XL 1200 Custom.
Kevin Cooper Did you do a tune along with the baffle removal and if not have you experienced any engine or valve damage?
Correct me if im wrong, but want you burn the jugs up if you do this to a fuel injected bike?
Well done!
I have a 2012 sportster xl1200 custom and got slip-ons and the Harley shop told me I was fine but if I were to straight pipe it /remove the baffles I would need a fuel programmer. Because it will burn the valves. I now have a heavy breather with rush slip-ons and a screaming eagle race programmer and gained 20hp 15ftlb torque and about 10 mpg. I would recommend the programmer if you don't want to put unnecessary money into your engine. Ps fuel injected need back pressure to run correctly
Great work guys. What a difference in sound!
Just wondering since we make license plate backers if that extended backer you have is for a military sticker?
Well all of us in this video are US Army NCO's. But the backer is for the Texas safety inspection sticker.
Nice mod. I doing this in a few mins. Time for the neighbors to wake up!
Michael, you need a bike first brother. Keep it real, real dumb
anyone know what size hole saw I'd need for a 2012 RK FLHR?
Nice bike... and nice boots btw...
I had a buddy knock mine out with a long steel pole and a big hammer custom Sportster 1200
The issue with both burnt valves and low end torque is that, because the exhaust has better flow, the engine is now getting more air. If they have this, along with other mods, they could be running too lean causing both of those issues.
My bike has 8000 miles and hasn’t had baffles in it. Lol
Do I need backflo preventers for a 1200 sportster if I take the baffles out
torque cones work well
I have noticed that on the newer bikes, they have a catalytic converter in the front part of the slip on, that is a whole other story!
I dont this on my 2018 883 and couldn't get baffle out.....ran into about 2 inches of steel mesh in the top of the pipe...do you know if they changed the exhaust on a 2018....or is there something else I need to do to get baffle out?
Yeah, they did change them. I think around 2013 ish? So slip ons are best now id say
do you need to tune the ecm with this mod i have a 14 iron
Neil Bob yes you will if you want optimum performance.
I bought a 2018 sportster 1200 iron can I do same willl I need to tune or will I just get less gas mileage not worried about the mileage just thought I asked b4 I start wrenching on it
Marisol Macias I think the newer ones have the catalytic converter in the slip on itself you might want to check if it is they're pretty hard to get out and you might just want to purchase some regular slip-ons

For future reference a 2" hole saw works really good and you don't have to clean up the cut.
Hey Chad,
I have a buddy with the 100th aniversary edition 883, he doesn't have the $ for all the aftermarket stuff but HATES how quiet the bike is. Its his first and he wants that sound. Any effects of performance or longterm damage concerns before we do this?
P.S. thank you to you and all the others who serve.
Well, here's the skinny... It will sound better after doing this...you will lose a little low end torque. And she might pop a few times here and there.

did you do this to both pipes or just the one? I recently got a seventy two but it is to darn quiet.
Both
@Ruben, You can get the computer re mapped.
What if you just remove the muffler and leave it off?
Did you guys had to re-jet the carbs?
efi... no carbs
I can smell the metal grinding in my house 😂😂
I drilled 3/4 inch holes in the baffle on my 04 sportster 1200 instead of removing the whole baffle. It sounds pretty good! I made a video with the sound so you can hear it.

hi! I've a sporster from 2003, can I do the same thing from the video for remove the baffles. thanks!. regards from Spain
yes you should be able to
Thanks for the real way to remove the baffle. Other Dudes are using long drill bits,
+David Spennachio A hole saw is best, but pricey.
I just bough a new HD sportster 48, 2017 model.
I want to remove the baffles from the stock pipes.
Does anyone knows and help me if this action will create any problems to my HD.
Do i need to do anything else after removing the baffles or would the removal be enough.
Thanks
You should get the computer remapped. But a '17 probably has the cats in the slip ons, which is very hard to get out. I would recommend a set of cheap slip ons instead. You can install some torque cones if you don't want to re map.
I've got a 2000 Sportster an it has the two pipes that turn into one muffler. Is it the same concept with it?
You would have to look into the slip ons, but most models past 2012 have the cats inside the slip ons, I hear you can get them out at great effort, and heard it's just better to buy a slip on with no cat.
I have a 2009 1200 sportster, I want more noise, trying to figure out getting rid of the baffles, I’ve heard that hurts your low-end torque, and can mess up your pistons, you have to adjust the fuel flow?
Yes and yes, after this or adding slip ons, you should remap the ecu
Hey, remap the ECU once? Or do I need a fuel flow regulator or something...………Thanks
Did this affect performace at all? I want to do this to my 2015 Sportster.
+Hector Delgado it should, but you will want a fuel controller because it will run lean. Newer Harleys cone from the factory really lean due to EPA BS anyways.
