Mac midlegnths in NJ and mobile inspection

I was thinking about putting Mac midlegnths on my LS1 with the catted y-pipe. Can someone please tell me strait up how legal it is to put these on. I know I will fail visual but will they pass the emission part of the test? Has anyone here actaully failed the visual test with catted Long tubes or mid-legnths?

Another question...

I have been hearing a lot about these mobile inspection things.
What are they? Would they fail me for like an aftermarket air lid and would they fail my midlegnths? And what is the penality for failing them (dollar amount and other stuff). What do they look like and where are they also (my father and I have never seen one..we live in central jersey)

Thanks!!

BTW..my car has 79,000 miles and will have about 82000 in two years for my next inspection (living at school with no car means no driving....) The reason I put this is because I have heard that if you go past 75,000 miles..you can change your cats.

Mobile inspections have been around for years... but in recent years they have been cracking down and using the mobile inspections more frequently.

To put it plain and simple... if the headers do not have a CARB number they are not legal.

If you have no cats on a CARB approved header you are not legal.

If you change the location of the cats from the original factory location it is not legal.

If you get caught by a mobile inspection stop... be prepared to pay big time fines! no $200 here, we are talking thousands of dollars.

Many people have passed a snif test with illegal headers. but its still not legal. And a mobile inspection crew will know were and what to look for. Their job is to catch you cheating the system.

This is 1 of the reasons why I just took my car off the road.

Past few years theres no such thing as "easier places" to get inspected....I tried in my 97 years back and got my balls busted wherever i went...even one of my uncles mechanics (freehold chevy) wouldnt even pass me cause of fear to loss his license...jersey blows plain n simple

Now I knew most of those laws but I am still trying to figure out if the 98 Mac midlegnths actually move the cats. I keep looking at the picture and then looking under my car and it looks the same.

Cat on the left moved up towards the manifold and the cat on the right in the middle of the y-pipe. Is my current car not supposed to look like that? Any one got a daigram of a stock exhaust 98 LS1?

Thanks!

Simple way to know... are they CARB approved? If they are then there is a CARB number supplied by the manufacture that means they have been tested and checked out ok. If they are not then there is some reason they are not. It could be alot of things... 1 being that the cats have moved. Even 1/2" off from stock and they cannot get CARB approval and therefore are illegal.


I dont know off the top of my head weather the MAC midlength headers are CARB approved but my guess is that they are not. That is because they are "mid lenght" headers. But to be absolutely sure call the manufacture and ask if they are. Then get the CARB number to prove it.

they move the cats. i have them, and yes they move the cats

i have jet hot long tubes. i went through state inspection facility earlier this year with them. 45k miles on car. they didn't say a word about them. i actually went through twice. first time i failed because i forgot to hook up my front O2 sensors (just did tranny install and messed up with the connectors). so they said i probably have bad o2's; fix them and come back.

i went home and saw my mistake. next day i went back and they were all over my car. it passed the OBDII test since there were no SES lights. they don't do emissions testing on cars with OBDII in NJ. but then they saw my exhaust cutout (which was obviously capped) and they failed me for that. i went to private facility and got passed.

but moral of story is the state inspection didn't say a word about my car's long tube headers or the obviously not-stock cat placement.
hope that helps.

Sometimes you can get away with it in a state inspection line... they do so many cars that its easy to miss if they dont know what to look for. I passed a state inspection with tinted windows... they just didn look. They were yaping about who was going to win the game that night rather than paying attention to their job.

A mobile inspection stop are looking for that stuff.
