Insane? maybe a few-15hp? Is there a reason you can't do long tube headers? I think getting the exhaust in general free (er) flowing would be better for starters, beginning at the exhaust manifolds.

catbacks are a waste of money IMO.

Best is a cutout and a stock muffler. Noise when you want it and stock quiet otherwise.

Well when we opended the exhaust cut-out the dyno showed 14 Ponies more. Then when we removed the air filter it showed 3 Ponies more on the 3rd run. they are out of order 1st run left alone the 2nd run shows final run w/exhaust cut out open and no filter and 3rd is with cat open and filter on. thats just the way it was put on the dyno sheet
