hey guys should i go with 3 inch exhaust header back or should i go with a back pressure system i dont know somebody helpp!!! thanks

If its a non turbo car then you will benefit low end from having a little backpressure where Turbo cars just need to get all the air past the turbine as possible so bigger pipes work better.

Do a little research, turbo back exhaust setup with stock tune can blow your engine.



Gauge what your goal is (power, sound, looks). Then decide if you want cat-back, or turbo-back.



In my opinion, Racing Beat makes the best exhaust.

we've done a couple cars using the RB down pipe and presilencer, and then pick your can out back, the RB presilcener makes anything streetable
