Stillen b-pipe vs. courtesy
#2
Stillen = loud (no resonator)
Courtesy = quiet (small resonator), nice build quality
Both make about the same power. Make sure that if you get the Courtesy B-pipe, skip on the extension piece they'll send you. It is way restrictive. Just have a shop fabricate the extension. Check out my site for pics.

Umm...no not exactly.
First of all, b-pipe and muffler doesn't really affect hp, at least not on Maximas. We only gain 3-7hp. Y-pipe is the main resistriction. Mandrel bends only make a big difference if you're car is pushing out 300+hp. Otherwise on a NA car, it doesn't really matter. Anyways, custom mandrel bends are very very $$$$.

Well my B-pipe must have done something......
because by just adding my B-pipe, I dropped .2 in et and gained over 2mph in the 1/4 under the same conditions and similiar 60 foots. I noticed a nice gain in torque and upper rpm hp and so did Greg P.
