    i have a 1995 gm 350 crate motor and i am going to run hedman long tube headers and duel exhaust out the back with a cat and flowmaster 40 on each side. i will install a cross over pipe - where it will fit best. my question is, should i go 2.5 inches or 2.25 inches on my exhaust tubeing?

    On a stock crate motor?? I'de almost consider running 2" pipes. Backpressure is your friend!! But if those are your only options 2 1/4!!

    I'm told, and run 2 1/4 duals. "headers + 2 1/4 duals=good back pressure=low end torque." /forums/images/graemlins/thumb.gif
