Flowmaster Original 40 vs Flowmaster Super 44
Sorry for the low volume. 1970 Monte Carlo has a fairly stock 350 with Hooker 5/8" Competition headers, and a true dual 2.5" stainless steel exhuast system passing through two Flowmaster Original 40 mufflers, and exits from the side. 1974 Camaro has a mild 350 with Hooker 5/8" Competition headers, and a true dual 2.5" stainless steel exhuast system passing through an h-pipe, then two Flowmaster Super 44 mufflers, and wraps over the rear end and exits out the back.
