mugen exhaust
you know how the mugen exhaust necks out from the cat to the resonator at 2in , and then at the end of the resonator its a little bigger through out the whole system. can i cut the part before the resonator off and weld bigger piping on it or does the resonator start at 2in and gets bigger at the end of it???
Every JDM cat-back exhaust system (except 1 or 2 straight through and under-the-axle design) will have small bottlenecks in the b-pipe. Why? Maybe it's to produce a desirable flow characteristic which can't be achieved by having a straight pipe design. Possibly, bottleneck is good for throttle response and/or midrange gains.
All in all, I wouldn't chop up Mugen exhaust to eliminate the bottle-neck. Mugen knows what they are doing... it's not there for aesthetic reasons.

Bottleneck in the b-pipe after the cat is to slow down the flow just after the cat to maintain the temperature of the car...Cosworth wrote:Every JDM cat-back exhaust system (except 1 or 2 straight through and under-the-axle design) will have small bottlenecks in the b-pipe.
