So after looking at some pictures the cats will be around where the stock cats would have been placed. Thanks for the suggestions, those are really reasonable, about what I'd pay a private shop to inspect it actually. So those slip over the exhaust and you weld them in, or butt fit? I imagine the exhaust will be a little quieter with cats on it as well, its pretty damn loud right now...lol

most I've seen are slip on and weld/band clamp.

I can't remember, I had a shop weld mine in, and I used new pipe since Chevy trucks use odd 2.75" pipe size. They probably slip over pipe of the same size, like mufflers are supposed to, then you could weld or use a lap-joint band clamp. I know auto parts stores sometimes rent pipe cutters and benders, usually with an expander so you can modify the pipe to fit as needed. I'm terrible with that stuff and usually make it worse but you can probably make it work.88 Town Car (wrecked, for sale)

The ones I've seen were also installed basically like a muffler, slip-on and clamp or weld.
I suspect the cats will be more visual for you than anything else. A halfway proper running EFI 302 almost has to be cleaner than a 1974 carb V6. Much looser emissions standards for that year anyway.86 Lincoln Town Car (Galactica).

Maybe if it came with one from the factory it has to, no matter how old. I know the Mustang didn't have cats until 76, so you could get a 75 model and put a hot 302 in it and not worry about emissions.88 Town Car (wrecked, for sale)

Visual inspection to register? I have that here. No e-test once you've plated it if it's older than 88 but if I were to sell it factory emissions stuff would be part of the safety certification.

If you tag it with regular plates, yes. As far as I can determine, if you put standard plates on your 1915 Model T, it would have to pass the sniffer.Originally posted by pantera77 View Post

We don't do safety either, just a sniffer up the tailpipe and a visual check for cats if its supposed to have them. You *may* be able to argue having cats on stuff that may or may not have had converters depending on date of build, engine, etc. I wouldn't expect the people at the inspection station to have any damn clue what you're on about though. I know they don't do a real check of the emissions equipment. I've had no pump on my car for about 9 years now and it has never been failed for it.Last edited by gadget73; 12-16-2014, 08:34 PM.86 Lincoln Town Car (Galactica).

I have no doubt i'd pass based on the emissions standard of 75 with a FI 302 and cats: http://www.state.nj.us/dep/aqm/Sub15.pdf page 13, you can see in 75 they lowered the rating because of cats, it's really not that much higher than 81 and up.
Just looked through that link I posted. According to all the legal mumbo jumbo, The car will be checked in accordance to 1975 vehicle standards. Engine swap is legal, BUT no emissions controls can be disconnected. I will print this out and take it with me to inspection if i get an argument.Last edited by Brown_Muscle; 12-16-2014, 10:53 PM.-Phil

I wonder if they mean 1975 emissions devices, or emissions devices for whatever year that motor is.
Honestly though, if they don't ask questions, don't give them any answers. Don't be surprised if they just pass it as a bog stock 1975 Maverick.86 Lincoln Town Car (Galactica).

If it's running right with cats, it will most likely pass. Like Gadget said don't offer any info unless they ask. I'd also go to Deptford when it's busy less chance of BS.2020 Volvo XC90 T6 Momentum (Ice White / Blonde)

my cats are shot too. donŽt know why, i bought it with empty cats. so in august i welded some universal converters in... in october they rattling again... i got no codes, nothing... bit the exhaust gases are very hot. than i looked closer to the exhaust setup.... california cats (these 2 piece unit with the air injection tube between the oxi and 3 way converter) and then a real y-pipe wich goes into a only 2" diameter pipe. thats the reason why the cat gets toasted: too much restriction in the entire system.
next year iŽll replace the old pipes and go to duals. bought the h pipe and tails (i use the sedan tails) and i switch to metal-cats. when you replace old stock ones with new metal catalysts (they sell universal cats up to 4 liters here) you can get to a better emission class, that saves you a lot of taxes
so iŽll weld to of them in place where the rear ones are, still thinking about the air-injection in front of them, should i disconect the hose or not...
so iŽll only have two cats, but they give me a better emission class. i hope all the things are working right and the metal ones donŽt get toasted (thinking about replacement cats from rockauto... but.... i didnŽt know... any sugestions?)
greetings,

If you get the car inspected privately, do that. They should be able to pass the Maverick without cats. Yes, you would have to pay for the inspection fee, but it would be less than getting a free inspection from the state with a fail sticker. Then you would have to do the work anyway.
