I have a 2001 f150. I am thinking about putting hi-flows on in the future(when I get a job and money). I am reading the laws that are in place here in NC and I think, if I understand it right, that all they do is the OBD test. So does that mean I could pass with only 2 hi-flows and possibly a tuner or something? Any help on this and the emissions laws of NC is much appreciated.

Thanks,
JP

P.S. I live in Granville County which I think I saw listed as an emissions county.

 

You should pass. The only thing they may give you grief about is since your truck came stock with 4 and it only has 2, but it will past the sniffer.

 

Ok thanks, but I would need a tuner also to pass right?

 

A tuner would be a great addition but its not needed to pass the inspection as long as the high flow cats are installed.

 

Ok thanks!

 

in MN its just is it too loud or not, and that's a judgment call by the cops. there arent any epa standards upheld by the state...global warming my a$$

 

haha. I wish NC was that way because I would have already done this. I hate all these laws like tint and emissions.

 

dude you can run whatever the hell you want. ive never ever had a guy inspectin my truck even question my exhaust. even when i had her straight piped. even if they do give you grief, so what? there is a place that will do inspections every half mile. an extra ten will "convince" most guys to let most anything slide on an inspection.

 

dude, its an emissions county..you CANT run what you want to..

 

f150fella, I read that in the emissions county they only do the OBD port, so that would mean I would pass with the hiflows right?

 

You should pass. Where I live all they have is the OBD II test as well. I passed with hi flows of 2 different brands many times. I even had a fully blown out cat once and it still passed! Now I have the rear O2's turned off in my tune, and no rear O2's at all anymore after my new Catco hi flows. I guarantee it will pass again. I'm always nervous pulling into the bay with my loud exhaust and even louder screaming Procharger whine....the guys always give me funny looks LOL. But I always pass with flying colors.

As long as you have no check engine light/ DTC codes in your system, you should be good to go
