Will putting and O/R h-pipe and magnapacks help performance on a stock 2001 GT at all? My only mod so far is 4.10 gears, and it's a daily driver.
I want to do the exhaust mainly for sound, but is the lack of backpressure going to hurt performance?
So would a catted H-pipe be better on a completely stock GT, or will an O/R h-pipe be good? I want to go with an O/R h-pipe for the sound, but not if it's overkill for a stock GT and is going to hurt performance.
Thanks!
