There are alot of guys with long tube headers and other mods that make their car obviously not able to pass emissions. What do you guys do about it? Just take your chances with an expired inspection, pay someone off, go to camden...?

if you have to ask......... :wink:

anyone with obd2 can pass emissions as long as they have cats and a good tune........i dont see why obd1 cars wouldnt pass the sniffer with cats and a good tune...

without cats, well... your better off pm'ing people that you notice mentioning it in their sig, because no one will post publicly about inspection hookups :wink:

Everyone pass's w/ lts just make sure you have cats/air hook ups

They make emission's longtube headers so you can install them and keep your car somewhat legal. OBDI will still need to pass the sniffer so dual cats would probably be needed along with a tune to make adjustments.

So you guys are saying with LTs and dual cats, you pass visual?

should be fine

Hm ok, now what would happen if you pass the sniff test (OBDI) but fail visual? Is that just a total fail?

Mike

01-13-2009, 01:23 PM

yes. its the same as passing the obd2 scan and failing visual....

Why wouldnt you, inspectors dont know the differance from one header to another...there just looking for the cats

The header has nothing to do with it, the location of the cat is what is important here. And since every LT setup moves the cat, its illegal.

No kidding, what im saying is they dont know the differance if there moved from the original location or not...Knew more then a few people fly through Nj inspection w/ catted LT lsx setups. Most places dont even look under the car as long as everything emmisions wise checks out.

Ok, come June, I will go through, if I fail, its your fault.

my grandma can tell the difference.

i think if you fail a visual you might not have to pass emissions again. not to certain though.

like everyone has said, you can legally run long tubes.

If you fail anything they run the whole car through again anyway. Years ago it wasnt like that.

if you fail the safety portion of an inspection and pass the emissions, you will only need to pass safety again as long as you reinspect within the time limit. i am not sure if cats will fall under safety though, i doubt it actually.

you may get lucky with going to private shops or state inspectors not popping hoods, but cats not in the stock location, missing, or emissions equipment tampered with is a failure and possibly would have to return to a specific state facility where they are super anal and will want to see everything is perfect.

my car only has one cat, and I plan on getting them after I get a DD so i kinda don't want it to be legal.

Plus I also have tinted windows so no matter what I'm failing.

eh, unless you are building a race car you will want an inspection sticker. they are over $100/ticket for failure to inspect

I reccomend keeping it legal. Alot of these guys run around w/ ory's because there alot cheaper. If they ever run into a emmisnions checkpoint there screwed. Theres not many of them but they exist. Not sure how your getting by w/ the tint. When I bought my 97z it had full tint and I was pulled over 4 times in the matter of 2 days. Im driving around right now w/ my license plate in the window trying to duck cops :lol:

I've lucked out with the tint.. I don't drive around alot though, basically school is it.

i have been stopped twice for tint in 4 years. it depends on the town

Yeah, but an inspector can't see down inside the engine compartment to find the exhaust manifolds or headers on a 4th gen. The closest thing to truly legal would be the MAC mid-length headers which might put the driver's side cat in the right place on an LS1 car. The old ASM mid-length headers for the LT1 worked well and gave the ability to keep the cat(s) in the stock y-pipe location. LT's are only worth 2-4 hp over the ASM mid-lengths. George Baxter was making over 700 hp with his setup. As for the ORY, it's pretty easy to add dual 3" cats to an ORY and you can usually find them for sale used or cheap on LS1Tech or Ebay. As for tint, that's just another excuse to get pulled over and then they'll check for other violations! :nod:

What ever happen to GB, I remember years ago watching him make a few 9 second passes @ Etown in his anniv. vert.

Ok so question for you guys. I have been wanting to put LTs on my car forever but I need to have a cat. Here in Pa we only have a visual but I dont want to be dealing under the table to pass inspection. What do I do if I want a set of Emission capable LT headers but still need a cat?

Mike

01-13-2009, 09:26 PM

buy a y pipe with a cat?

LTb1ow

01-13-2009, 10:23 PM

Would one cat work? I would think it would be to far from the headers to work effectively.

It really just comes down to where you take the car. You hardly ever hear of a car failing because of longtubes.

The issue is that although most places will put the sticker on the car, if a cop stops you and wants to go over the car and write you up. It's unlikely you would get fined for the headers or cats not in the proper location, but having no cats could get you a ticket.

1994lt1 - there is no such thing as a "legal" longtube header for our cars. To be leagal the header must be C.A.R.B. certified, and since LTs relocate the cats, they will not be certified and legal, even if they have the AIR fittings. The only headers that are C.A.R.B. certified would be shorty headers, Edelbrock and hooker I'm aware of.

That said, if all you need is a visual, as long as you have the cat you should be fine. I'm exempt ( drive under 5K a year) and what I'm running longtubes with the AIR fittings and a Y-pipe with a cat on both sides and I never had an issue. How many people would look under the car and know it originally had one cat, and now it has two or would really care that it has additional emmission equipment.
