I have run 4 different BB engines on my revo...I always used an RB pipe, HPI Ripple Pipe, or the CVEC BB pipe for revo.....following the advice of a member of another forum, I tried a new header and side pipe configuration with my mach 28 - quite a bit of difference! More power everywhere with the side pipe then my cvec pipe! The Mach ran better also (idled better, no flameouts, etc). I am a believer in side pipes if you are running a BB engine in the revo...I should have done it sooner! Also, the pipe is more secure then any of the "regular" revo pipes on the back...no more busted gs couplers for me!
