hey guys I'm just wondering what kind of bad or good experiences you NC Z owners have had with passing or not passing emissions. The main things I'm wondering about are the common NA mods. I'm pretty sure the test pipes wont pass (correct me if I'm wrong), so I don't think I'm going to go that route. But I am deffinitely doing a 5/16 spacer, mrev, jwt popcharger, exhaust and hopefully headers. Should I pass with this setup? If not which one(s) of these would cause me to fail?

 

spacer and pop are definately not a problem, not 100% on the others though, i don't see why you would not pass with those mods

 

I believe it is different per county here in NC. But I have had no issue with my car (twin turbo, full 3" true dual exhaust, plenum, fuel system, ecu, etc etc) as long as I put my factory cats back on to pass the visual inspection of emission devices and there are no CEL's. I have had it inspected twice since the TT install and there were no problems.

 

No problem with my car passing either with all my NA mods.
