Question for NH guys with catless downpipes

[MBoss_F86]

How do you guys pass NH state inspection with catless dps?

I recently moved to NH from NY and want to register my car here in NH. I have RK catless dps with MHD tune. I turned CEL off in MHD app. Is it enough to pass state inspection? I don't have CEL or any codes.


Thanks

You didn't have a problem in NY? When you say shut down the CEL, do you mean you're just shutting down the downstream O2's??

My mechanic in NY passes my inspection, I've been going to him since 10 years. He knows about catless dps, he checks everything else before slapping the sticker on.

I just turned CEL off in the MHD app and said I have aftermarket dps

No, I am getting different opinions here. I had new tires installed last week and the guy there said my car would pass NH inspection since there is no CEL. But I have to change my registration to NH first. If the inspection fails after that I will forced to install OEM downpipes.

You can register on line in VT with ZERO inspections, just need proof of insurance, residency does not apply. Just deal with the green plate. You're welcome.
