i would really like to see what a good header and hi-flo cat would do for your car black, I bet it would help the exhuats get a bigger gain and get gains of their own, as well as the intake, as much air as an intake pulls in the exhaust has to put out.
ever notice the companies that build 500hp beats like FEED, and Bozz use like 3 or 4 inch pipes for intakes and for exhausts they all use 2.5 to 3 in titanium exhausts, if a part has potenetil gain in it they know how to make it show its full potential.
damn rambling again.
