buy a high-flow catalytic converter from a reputable parts dealer, not ebay, and take it to a shop to have it installed. if it hurts your "hp" at all, it will only be a couple. Nothing you'll ever feel. its not good for the environment or your car for it to be running without a cat.

Umm I'm not an expert but I would think high flow allows easier flow of air through. Btw... do you have an EX? The EX the cat comes separate from the exhaust manifold but if you have an LX or DX then it comes with the exhaust manifold as one piece.

I think that is only true for the 96-00's. The 01-05's all come with the cat built in. I could be wrong though. I am too lazy to look it up.

No... I have an 01 LX. The LX and DX are built in :/ but I called the dealer to see if I could get a new exhaust manifold/cat off an EX for my LX and he said no because it's in two parts. Unless I guess the dealer could be wrong...
