Rinehart 3.5"
D&D 3.5" slip ons
V&H hi output slip ons
Listened to tins of clips and trying to find the loudest of the three.
Wad looking at the fuel moto ones but they recommended the rineharts over the jackpots.

 

I've heard all of those on 96" bikes. I'd say the Rineharts were the loudest, then D&D, then the V&H. For maximum effect, you need to run an aftermarket header, or at least cut the cat out of your stock header.

 

I have a set of catless 09 hd headers. Thanks for the info. I am leaning towards the rineharts. Was told 3.5" are a bit louder than the 4".
