Harley Davidson 2024 CVO ST Muffler modifications

This video shows how I removed the restrictor and fiberglass wrapping from inside the Harley Davidson 2024 CVO ST OEM mufflers.
This enhances the sound profile of the factory mufflers - making your CVO ST sound louder and deeper.
This is Part 1 of 2.
Part 2 shows the reassembly.

Good job! Nothing is more fun than taking brand new mufflers apart.

[@PapaBiker]

Thanks! You guys are the best!

[@mojo4376]

Great job! Can’t wait for part 2 with the new exhaust sound and performance.

[@PapaBiker]

Thank you! I’ll have a video out with the sound very soon!

[@coachdbright]

Okay waiting on part 2 and the sound comparing

[@PapaBiker]

Soon!

[@antmrod1972]

Great video and detailed explanation. One question thou: could you be able to remove the rivets remainings from inside the muffler without removing the last end cap of it? Something like turning it up side down and shaking it until they got out... Thanks. Ride safe and yes... also waiting for part 2 😎✌️

[@PapaBiker]

Part 2 is out! I’ll do sound in another video…

[@PapaBiker]

@@antmrod1972 Unfortunately, you must remove the carbon fiber tip and cap to remove the rivet parts. There is no other way to get them out.

I bet it runs like crap now

[@johnnybotello4304]

Awesome video man

[@PapaBiker]

Thank you!

[@joedanreed]

Great video. I would like to keep my exhaust as well if I could do this. Don't know if I have the patience, but may give it a try. Thanks for the video.

[@PapaBiker]

Thank you! Give it a try! It’s really not that hard, and fun to do!

[@dieselsoggydog6299]

One would think if you can afford a CVO ST you could afford after market mufflers or even the whole exhaust system.

[@PapaBiker]

It’s always good to save money! 😃 But I really like the look of the OEM CVO ST exhausts, and they weigh only 12.5 lbs total! Great sound now too!

[@seeda3473]

I mean carbon fiber is cool, why trash it?

[@PapaBiker]

@@seeda3473 Carbon fiber is still good! Just improved the sound of the exhaust. Thanks!

[@rexnhogz]

In his defense they are titanium and extremely lightweight

[@mattjad3473]

Very helpful video. You mentioned that you could stop if you only want to remove the restrictor but then how do you remove the rivet ends? Can you shake them out! Thank you.

[@PapaBiker]

Oh, a misunderstanding…. 😔. You need to take off the carbon fiber tip and cap underneath to remove the rivet shafts. Sorry!

[@mojo4376]

Just an idea. How about a strap wrench to remove the carbon fiber cap instead of a hammer?

[@PapaBiker]

Hmm.. 🤔 Maybe! Thank you for the suggestion!

[@robertmercurio2859]

Did you do a sound comparison yet? Great video

[@PapaBiker]

Not yet! Soon!

[@robertmercurio2859]

Thank you

[@miraziztoy]

What happens if you put holes into the restrictor and put it back? do you think you will have some back pressure? just an idea...

[@PapaBiker]

You will definitely have more back pressure with the restrictors in place. I just don’t know that that it would make much of a difference, as the pipes without the restrictors have a fair amount of resistance back pressure by themselves. Only way to tell would be to dyno the bike, before and after to see if there was any HP loss. 🤔

[@mountainmusclecarsclassics3172]

Did your check engine or fi light come on after this? Did you lose power ?

[@PapaBiker]

All ran well! Don’t know about any loss of power…. At least I didn’t feel any. I didn’t do a before and after dyno test.

[@ComplaintFree]

Good morning hope all is well,how many miles did your bike have or those cvo st mufflers had when you did the extraction of the restrictor & fiber thread? I only have 14 miles on my bike lol it’s too quiet

[@PapaBiker]

Not sure about the mileage before - as I bought these from another person. Sorry!

[@ComplaintFree]

@@PapaBiker thanks brother I think when I have a 100 miles I’ll do it😎

[@PapaBiker]

@@ComplaintFree Just a heads up - the more miles on the exhaust, the harder it is to remove the fiberglass packing as it starts to break down and only comes out in pieces…

[@ComplaintFree]

@@PapaBiker ok so you think I should do it soon?

[@PapaBiker]

@@ComplaintFree If you are going to do it anyway, sooner is better than later. Otherwise you will need to rig up some sort of rod with a hook to pull out all the fiberglass.

[@dannykelly3464]

What I appreciate most about German Made Vehicles (BMW's), They are road ready from the factory. No need for all of these changes. 😂

[@PapaBiker]

BMW definitely make fine bikes! You don’t need to make any changes on a Harley. But one of the funnest things about a Harley is that you can make changes to make the bike your own. Harleys have a soul! 😃
