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.

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.

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.

try the sparkplug defouler trick. I had the same code when I put in my hiflow cat.
