How do I pass emission test with out a catylac converter...I have a high flow cat is there any way I can still pass without having to but a stock cat
 
If you have a highflow cat you should pass. Did you go and fail?
 
high flow cats dont do their job as well as a stock cat converter does FYI.

So if your creating a lotta nox oor somethin to begin with then that hi flow cat wont help you as much as a stock cat.
 
This is how you pass. Go to a place where they don't check it. My town has no E-checks,love it....

Very helpful. If you can't pass with a aftermarket cat then there is probably something wrong. I pass w/o any cat at all. Check to make sure your EGR is functioning, O2 sensor is still good, etc.
