Test pipe, do they really do you any good?

Cheers Fatboy!
So glad he talked me out of it :)

If it's just resonators, it's no biggy.
I've had 2 removed and only left the CAT + muffler on a 2.5" system.
You get more of a open sound, more bark.

Previously had no CAT and below 4,000rpm it was kinda annoying. More reason to stay above 4,000rpm I say :)

haha forsure! only thing is ya use more petty offcoarse..it's a trade off.Sometimes I put in $50 and have fun.
