Who's successfully passed emissions testing with a cam?
 
Have to renew registration. Unfortunately that means a sniffer test. Will I have any problems passing with a 222/226 113 cam through stock cats? Thanks.

I concur... I've heard of people passing with 212/218, but I think yours is too big.

Actually now I'm not even sure if it's just an OBDII test or an actual sniffer. All it says is that cars pre-95 are exempt from testing. But I looked at the testing sites, and it's crap like Midas. So it can't be a sniffer, but I'll have to confirm.

Bullshit. If they plug you in your good. Almost positive your not getting sniffed, your to new...I have made it through plenty with my set up, no cats. It has burned our eyes at time of testing, the guys, I quote'' Man this things sounds like a race car'' Never no probs. No codes, obd2 you golden unless they give you a visual..

If it is just the obdii test. You can run an readiness test with efi live to see if you will pass the readiness test
