Well, with a high flow cat it is a 50/50 shot you will get an SES light due to o2 readings, some do some do not
o2 sims are supposed to cure this but in my case it did not :(

The highflow cat will probably throw an O2 code. You should be able to just hook it up to a scanner and clear it.-James<br /><br />\'96 3.8L A4 Camaro (SOLD)Comment
