Vance and hines twin slash dead horse question
« on: April 25, 2021, 01:47:43 pm »
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!!!! ;D 

They're still loud when I twist the throttle, but at least my neighbours don't hate me!
NOBODY hates winter more than a Canadian Biker!

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.
