If i buy a axle back of an exhaust system in this case a fujisitbo axle back, and go to a local muffle shop and get a custom b pipe with the same size. would it hurt the performance? since the fujisitbo is 2.38 and i would get 2.38 b pipe would that be a good ideal.

 

if you're going with custom, avoid crush bent pipes..go w/ mandrel bends
