Im thinking of just picking up a test pipe with a o2 bung and diong the non-fouler. I live in FL anyway, we don't have inspections.
its probably just in the numbers. kinda like 125.56 wheel tq stock versus 125.55 with the test pipe lol. i dont think a cat/test pipe could effect performance THAT much really...only with the combo of upgraded header and exhaust would it make any bit of difference. the exhaust piping/diameter/bends etc. makes more difference than anything in the exhaust stream. ive heard that a "high flow" cat doesnt do much in our cars anyway. get a test pipe and let it ride if you dont have inspections.BlkCurrantKord said:My cat's gutted, only difference I notice is more noise. I don't know where this less tq BS comes in, feels the same to me.
