If i had to take a guess it would be P0420 - Catalyst efficiency below threshold (bank 1)

Hmmmm. a new exhaust or a cat other than stock would throw a P0141 code for the heater circut.

I would get the new exhaust if the money allows, and buy the O2 sim from PFYC.com ;)

Yes, if it's not stock it WILL throw a code

run a str8 pipe

Illegal, and big fines if you get caught
