i had a FMIC on my car and didnt get defected for it
only got done for loud exhaust BOV and pod
had to go to EPA for the sound testing
thats when he sent me to the RTA for an emissions test. airflow issues etc and i think he saw my aftermarket computer
just get a new cat, a detune, heat the cat up before the test, good petrol and you can pass easily, but more money spent to get it to that stage
yeah penrith RTA is great, now if i get sent there again i can just use my old test and play around with it before i fax it off
