not if they do a sniffer and visual test without a cat

 

This is why i told him to go to a non full service testing facility. All they do is plug in, no sniff, no visual.... you will be fine as long as you have no cel

 

From my experience I passes the visual, sniff, and OBII scan with a Ams 50 Trim/meth, test pipe with a straight pipe with no resonator.

 

I guess it goes either way. I will have a tune, so no CEL. But if I fail Ill just put on the old system for the test. I had a mustang GT for my last emissions test with stright pipes and I passed... and that thing smelled of unburned gas like no other lol. I just wanted to get you opinions.
thanks everyone

 

Can anyone in Chicago/IL recommend a non-full service testing facility to pass emissions?
