Ok now i have your attention.
I need some opinions on exhaust size on a mildly tuned small block (395bhp).
Would there be any benefit to go from 2 and a half inch pipes to 3 inch,
or would this defeat the object of the excercise by causing more back pressure.
Running headers, crossover pipe and magnaflows at the moment.
