Re: Replace Stock Exhaust on 496?
I agree with Pure Energy. My $00.02 says that even if you get 20 HP at the crank, the expense is not worth gain unless your old manifolds are/or are about to start leaking. Save the bucks now and make them grow until you can (Upgrade engine, install S/C, Cam, heads, intake and carb/injection improvements.) How many of us installed headers on our old cars and without doing anything else to the engine saw an improvement, other than the "coolness factor, as... I got headers an' you don't". don't get me wrong, on the right engine Hi-Perf exhaust is a MUST.
