Paging: FAST4.8
#4
Well, your not gonna see any major gains with just about any exhaust like you will a converter or power adder. I would expect somewhere in the 1 to 2 tenths range. I never did a before and after.

I got 0.35 with my bolt on flowmaster exhaust. it was after the y-pipe. Single 3inch into a resonator(like another muffler) into a 70series (very restrictive muffler) and dual 2.5inch out the back. So if Fast 4.8 has true duals or a pretty good flowing muffler, you probably will see better gains than I did with my stuff. PS my exhaust is way different now. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
