How modified ? Check Engine lite work or on ? Details -----

Details....

PMs sent.

 

Yes off road H pipe on the car right now.

Put cats on it. Wham bam, it'll pass.

 

No reason to not run cats on a street car. Plus if you piss the cops off enough, they CAN gig you for tampering with a Federal emissions device (the cats). HUGE fines involved with that.

OBDII vehicle, all they do these days is plugin the computer to the OBDII port and that's it. Now the h-pipe and no Cats, well probably a problem being they do take a look at the underside or the vehicle with an under car fisheye camera that's displayed on the monitor next to the OBDII scanner screen

if you put the cat covers on the exhaust where the cat would be you might be able to pass

Bring it to a private inspection place, they may pass u for no cats

If its just a computer hookup and pass or fail I can see that, but if they have to do more, I think the days of tossing some coin for a pass are long gon in this state.

 

Ride a MC, avoided inspections.

Harry it's a 1991, OBDII wasn't until 1996. On an OBDII car though removing the cats or the guts would trip the check engine light, probably for Cat efficiency, this is because OBDII cars typically have O2 sensors before and after the Cats to make sure they're working.

Wow, was thinking 86 was OBDi to OBDII not 96, whoops, a decade off. ;(

Nothing like having a discussion about breaking the law on a public forum.

The state started cracking down hard on people getting shuffled through inspection a year or so ago. Something to the tune of $10k fine per violation, so all those "friendly" shops stopped pushing people through. Your best bet as mentioned is adding a cat. I have a good high-flow 3" cat from my F-body days in the garage if you're interested.

That could be fixed with a resistor.

 

For a hobby where you'll hear "you gotta pay to play" one should just get the cats for a street legal car. There are plenty of good high flow ones out there, and making clean power is very doable.

Spend the money and get high flow cats. Keeps most of the performance and can pass emissions. No need for this headache every time. Or just don't get it inspected and pay the summons whenever you get pulled over

Another option(considering the vehicle choice) is to get a second h-pipe that matches up to your headers but has cats. I know someone with a sports car who bought a set of longtube headers that offered both a compliant and offroad x-pipe, and swaps them out for inspection purposes. Takes about 30min to do and you're set for the next 2 years.

In the end its still a crappy rustang lmao j/k

We are not discussing anything illegal. Discussing the best way to pass inspection. As you can see 95% of the posts are recommending high flow high performance cats to be legal and not have to deal with the hassels.

 

Thanks for the advice guys I know I can always count on this forum for good info!

Shop loses inspection license too in addition to heavy fines. Nobody does that anymore for that reason. Liability is way too high, and you really don't want Trenton pissed off at you, there's a lot of other things they can do to make a shop owner's life a nightmare.

Register the car as either limited use or historic tags. It's 20+ years old, I do believe that will qualify. I have been told historic or limited use (I think that's called QQ tags) are exempt from emissions inspections. As long as the car isn't your daily driver, you should be ok.

Historic tags in NJ only apply to vehicles over 25 years, not 20. As for the emissions issue, depending on what exactly you have done to the engine, besides headers and x-pipe, a set of cats still might not be enough. A lot of the power enhancements one can execute on these days involve burning more fuel one way or another. That added fuel burning will by default increase your emissions. I would receommend putting the cat pipes on, and taking it through. Even if it fails, you have another 45 days to get ir to pass, but you also get a copy of the test results so you can see for yourself which gases are giving you the biggest problem. They are NOx, HC, and CO. excessive amounts of each give different reuslts. If you have an EGR valve still connected, make sure it works properly. You would be surprised by how many vehicles fail for NOx due to clogged ro restricted EGR valves.

Look into Collector Car registration. No inspection, and no age limit on the vehicle.

I just took my truck to the inspection station off of rt 70 today. Their was only one car in the building, I thought they were closed

I haven't had my truck inspected since it was due in 08. I need to do that at Some point this year

You will need to go through a private place or put your cats back on. Even cat covers and tuning the OBDII to fake the sensors I still failed.

As mentioned before car has to be 25yrs old in NJ for QQ plates. I have two inspections before I can do that. But thanks tho.
