Default NJ emissions

Thinking of putting headers and dual pipes on my 78. How do I handle NJ emissions? Car is not on road so I have time...thanks

Federal law trumps state law and states you have to retain the factory number and location of catalytic converters. Since the '78 only had one cat you need to stay that way. Headers are legal as long as they have the same smog provisions as factory manifolds. Aftermarket high-flow cats are legal.

It's then up to the state how much of that they enforce. But be aware that even if NJ does not check today, they can change the law and start checking at any time.

What kind of tags are you planning on using? There is no inspection if you run Antique tags. If you run regular use plates, you get an emission test once every two years. I have not seen them do a visual on mine, but with a '70, it didn't come with cats. The idea that you can't go to a dual system with modern high-flow cats, a better system BTW, is stupid. I know it is the federal law, but it is a stupid law.

But there's no IQ test required before becoming a law-maker.

Very simple, get historic registration and do whatever you want. No inspection and registration is free renewal through the mail every three years.

To get the QQ's you need to send two pictures.

My new toy (1981) has some mild modifications (see avatar), hood is a bit higher and grounds effects kit.

How strict are they in giving the plates? Would I get rejected for QQ because of these mod?

My 76 would qualify as it is totally stock but it goes through inspection every two years no problem.
