I run a 350 pontiac with dual 2.5" pipes, but I found this after the fact. I personally think that 2.5" is more than enough, but this is something to consider I guess. If you go to this website, scroll down on the right, and you'll find where it says "Exhaust sizing for power". Just something to think about.
