[Chevelle-list] Exhausts

[Jimmy C.]

I'm in the market for an exhaust system,I Have a mostly stock 454ci .60 over, mild cam with a street avenger 770 , stock open chamber oval heads ,super comp headers and would like to know if I should go with a 2.5"inch or 3" inch pipe. The  anyone has had any experiance with Pypes 3"inch crossover system with cut outs. looks like a nice system, but more expensive than Flowmasters.  Jimmy C.
