On a lot of posts about exhaust I see talk about hp and seat of your pants feel and so on, but how was the MPG? Did it go up/down? and what changes to the exhaust were done?
thanks for any info [sm=gears.gif]

Gas mileage should go up. On my vette, mileage went up after adding air intake, headers, exhaust, heads and cam. In the spring, I'll be adding a cold air intake, headers and exhaust to my Magnum.
