Sounds good do you have any check engine lights for the o2 sensor since you changed the cats I put a hi flow in mines and since I did that I get an 02 I even replaced and won’t go away

I did immediatly get the 02 CEI, didnt even idle for 3 minutes i dont think before throwing the code lol. But i have a trinity so the next day i had sean rewrite my tune for the headers and also cancel out the sensors. I think ive only heard of one guy so far that didnt throw the code with huigh flow cats. KOOKS makes the GREEN HF cats but are hella spendy
