I have a 1986 Chevy Silverado, I have a small block 400, decent cam, 650 double pumper, weiand intake, summit headers. What size exhaust pipe do I need to run, and what kind of mufflers? This is a street / strip truck.

Thanks,

Josh

2.5-3.0, Its going to depend on your header collector sizes, don't bother putting pipes on that have a bigger O.D. then your collectors, other wise your just wasting your money. Talk to the guys a your local custom exhaust shop, they'll fix ya up.
