Stock-ish 5.7 Build...2.5" or 3" Exhaust?
I agree with the crowd
I have 2.5 with borlas and a x-pipe on my 5.7 with a cam
sounds good and runs great. I have always heard big pipes for top-end power, but a bit smaller will help retain some mid range torque.
My 3" system cars always seemed to have more resonance too
