Yeah my car is still stock I don't even have an air intake hahahaoh, then your cat is probably toast. that sucks. you can get a cel eliminator/simulator to get the light off, but you wont pass emissions testing if you have to do a sniffer test.

I just pass inspection =) perhaps a megan mid pipe? And yup that's how I did the A/F

[AKEP]

did you get a printout on the numbers? post them up if ya did.

either way should be good, it might just be the o2. the numbers would help indicate the health of the cat.

i mean if you don't have to worry about a cat for a while, megan midpipe it is!

Or you can go race header with a O2 sim

def time for atleast a test pipe. WAY cheaper then a cat.
