CoolbaltSS07

I have a 2007 Cobalt SS/SC which I've recently installed a Vibrant header, cat, and 3" exhaust on. The problem is, I live in Ontario, Canada, and our new emission testers will not perform the e-test if a check engine light is on, which mine is. I had a friend who scanned it and it has to do with the catylatic converter. Just curious if anyone else has encountered this with the Vibrant cat or not. And if there are any other suggestions which may solve this would greatly be appreciated.

Throw your stock downpipe back on to pass emissions?

The first federal standards (Tier 1) for new nonroad (or off-road) diesel engines were adopted in 1994 for engines over 37 kW (50 hp), to be phased-in from 1996 to 2000. In 1996, a Statement of Principles (SOP) pertaining to nonroad diesel engines was signed between EPA, California ARB and engine makers (including Caterpillar, Cummins, Deere, Detroit Diesel, Deutz, Isuzu, Komatsu, Kubota, Mitsubishi, Navistar, New Holland, Wis-Con, and Yanmar).
