since you already have a y-pipe, the cat would be the next thing to modify in the exhaust. I'd say that it helped a little bit in the mid-range and top end. The exhaust note got slightly deeper at higher rpms, but it sounds sweet. It is completely legal and should pass emissions. You shouldn't expect anything phenomenal in terms of gains, but if you are going to mod your whole exhaust, it is the next step. I got mine from Phuong at GR Racing....

Re: Hi flow Cat
Nah, no noticeable difference. But, it will pass smog with no problem...especially if you let everything heat up real good. Basically, that is the only reason the pre-cats/cat are there...for cold starts, etc. HP/Dyno? It all depends...
Do you have leather or cloth interior???
