I am looking to free up the breathing of my engine to gain as much HP and plan on using a larger TB and MAF to go with my Monster Flow and BAT pipe on the front end, but am uncertain about the exhaust
If you were to make a single modification to your exhaust system, $ no object, which would it be. I have an SVT with the resonator replaced by a 2.5" straight thru .. Which of the following do you guys recommend and why?
High Flow Cat
Cat back exhaust
Headers ( Problematic, I live in Ca. with SMOG II)
Mufflers
other??? thanks jj
