any high flow cat is gonna trigger the ses light eventually, you need an o2 sim to prevent it or hptuners

Re: high flow cat

Yeah I would bet you are getting the post-cat code. If so, get it deleted and see what happens when they do the emissions test. Here in IL they just hook the scanner to the computer and if no codes come up you pass. They don't even analyze the exhaust gases any more (at least where I go). I have my post-cat O2 turned off and mine passed the test. I still have a stock cat, but like I said, they didn't even check the actual emissions on mine. They just scanned it for codes.
