RE: 80 series flowmasters
i will somewhat disagree. i'd say more around 5-7. if you didn't gain anything from putting on a freer flowing exhaust, then why do racecars cut off the exhaust after the headers?

RE: 80 series flowmasters
its just weld-in mufflers..... and racers typically have a much freer flowing engine, one that is pumping enough volume to actually be affected by its exhaust.
