i deffenitly agree with mr. blade there, i am kindda running a bottle neck if u think about it. But the most best thing to do right now is get the high flow cat. i think it will improve the car by a lot. I was just under my car the other day and i was looking at that damn cat and man its big, its got to go.
Ohh and yes, for sure i feel a difference from stock with i/e/h/and im. With a few more mods that i have like short shifter vtc afc, plugs, wires and a good suspension. Put some 100 octane fuel in there, let her ri[p on the high way.trust me car with be flying past a lot quicker than stock.
One more quick question is RANDOM the name of the high flow cat, i'll try to look in to it.

does anyone else have any sugestions?
thanks
