my exhaust helped a little. freed up the engine a little. i still have all the cats on tho. i prob only gained a couple horse...
id say a tuner is your best bet. then a camshaft and valve springs, headders, port and polish the heads, catbacks, and theres a lot of little things that might gain you another couple horses
