Pretty sure it wouldn't pass emissions anyways, but would it help any to run a cat with a cc306? I kinda wondered if it would eventually clog up the cat since the exhaust is fairly rich smelling with this cam.

 

I doubt the cc306 will pass emissions. I would just remove the cat all together...that's what I did

 

I've heard guys on here or LS1tech that have passed emissions with a CC306, however it takes one spot on or excellent tune to get it done. My suggestion, if you have to worry about sniffer emissions tests, save your self the trouble and stay away from the cc306. If you already have it do a search or contact Bryan at PCMforless as he can give you more information.
