I passed the Californa STATE REFEREE test. If I can pass that, you can probably pass any emisssions check in the world lol.

Haha. Did you notice any gains? Drift on E-H said he dynoed with the stock cat on and off and didn't say any gains or losses (shrugs)

cant say for sure because I put on my header, cat, and exhaust on all at the same time. So hard to pinpoint gains just from the cat.

Yes, it does. I just had one installed. Performance did change a little bit. Really when I am starting off from stop. But then again, I needed a new cat anyways. The ODBII was giving the Cat Insufficiency error. Bought it off of performancepeddler.com
