Vance and hines twin slash dead horse question

[Nitsujc]

Hi guys, I realize this has probably been beat to death as I did search and sort of got an answer? The links in the thread unfortunately dead ended. I was pulled over and given a vehicle inspection notice for my twin slash exhaust being too loud...long story short I'm now trying to hunt down a set of quiet baffles for it. I've found the part number 21899 in a few threads that apparently works but when I look it up it seems the size varies from website to website. Can anyone confirm a part number that does work with these pipes? Love the look of them so im trying to make them legal-ish

Appreciate the help. Thanks

Damn - I put the V&H baffles in mine, but that was 7 years ago, and I can't find or remember the part number....  I'll say they were a PAIN in the A$$ to put it - but worth it.

I DO remember setting off EVERY car and house alarm on my street when I rode past..... and getting noise complaints from Harley riders with open pipes, though!!!!  

They're still loud when I twist the throttle, but at least my neighbours don't hate me!

I think the 21899 part number is what you want.  I did some searching and, you are right, in that it shows a bunch of different sizes but if you dig deeper, you'll find that part 21899 is "1 1/2 in. quiet baffle for Vance and Hines 3 in. muffler"  In the below link, it says 2.5" but in the description, it does list it right.

Basically, find the best price for part 21899 and go with it.

I emailed V&H and they responded first saying that they did not do a quiet baffle for the Bolt part no 48531

I then responded and said I had seen 21899 being mentioned and the reply was that would not fit.

"Yes we were behind on the emails and have been working hard to try and catch up. But unfortunately, no, the 21899 does not work with this system.

According to this video (speed up to 13:40 in the video)

This part fit.  The whole video was them putting it on the bike.

The video is of 21897 and not the 21899 - but I have messaged Revzilla too. I just can't see V&H saying its not for the system if it is? I do wonder if it happens to be ok but is not officially but then I'd expected a slightly fuzzy response saying they dont recommend it or something?

My guess is both parts, 21897 and 21899,  wasn't made for the Bolt twin slash system but people have gotten them to work.  The good thing about the one in the video is that they put the whole install on youtube..
