Has anyone had any trouble passing inspection with long tube headers and OYP? I live is Memphis TN and all we have is the sniffer test. I have a 94 Z without a cat and i haven’t had any trouble passing but i am buying some pacesetter long tubes with emissions hook ups and just wanted to know if that will change anything. Thanks

 

If you're presently passing smog without a cat, I don't think there would be any change. Just make sure you don't create any header leaks that would throw off your O2 sensors.

 

Thanks thats what i wanted to hear

 

You shouldn't have a problem. Header leaks are not very common if you "cure" the bolts right and tighten them down as needed.
