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!!
