Hey guys, just wanted to get your thoughts before I start welding...

I have a 351W stroked to 393ci, 13.5:1 c/r, Weber IDAs, swesome heads/cam and etc. I built it to provide useable power to about 6400rpm.

For exhaust I'm thinking 1 5/8" header tubes to a 2 1/2" dual exhaust.

Or should I really be thinking 1 3/4" with 3" pipes?

Thoughts?
