Hello to all the LS1techers


i was wondering if LT's are SMOG legal where you live...(Visual,etc,etc)

I live in Cali. Where i think it's not OK...but correct me if im wrong.

LTs are techincally not 'legal' anywhere in this country, because they move the cats.

As far as what you can get away with, basically CA and some of the northeastern states are strict about it and will fail you for LTs. But in about 45+ states, they don't give a rats ***. I just passed the emissions test today (OBD scan test) and they don't even do a visual here in IL.

No, they are not smog legal. That hasn't stopped most of us, though

in florida theres no emissions testing, which means you can get away with just about anything

They apparently are legal in NM. I contacted the Emissions dept. and even went there in person to talk to the techs. As long as the equipment is present (cats, sensors) and it passes the sniffer, it is legal here. The best bet is to contact your local local agency and confirm it.

The actual illegality comes not from state law, but from Federal law. The Federal law says that you cannot replace a catalytic converter unless its defective and that you can't change a converter's position in the system...IMHO, as long as you comply with your local emissions laws, you should be fine ('cause they're the ones actually checking)...besides, there aren't many G-men out there checking vehicle exhaust systems!

Ohhhh....thank you all for yor post...and LUCKY TO YOU FLORIDA PEOPLE!!

and no one is going to stop me from getting my LT's...

although i'm broke right now...and saving up for a GMMG so...there's one thing holding me back

Couldn't somebody make a LT with a cat 'box' in the correct position of the original cat - only empty. That would pass the visual inspection, if it were required.
Just throwing out crazy idears...

where the "cat box" would have to go, there are still 8 individual tubes. that also doesnt take care of the "can't replace them unless they are defective" thing.

I guess I'm picturing the GTO exhaust that has both cats and resonators that look about identical

1. visually nobody could tell the cat's from the resonators - I'm not finding which is which in my searching this morning. I think LT's would fit before the second box inline.
2. I'm sure I could find a mechanic to sign off that my cat was plugged and I needed to have it replaced.
Since MI doesn't have any testing - I'll probably be ok. I do plan on putting the stock system in the rafters of the garage just in case when I do the headers and full exhaust upgrade next year.

Being 'defective' is not the only criteria for replacement. If you read the USEPA guidelines, you will find that a 'missing' cat also constitues replacement as well. So your exhaust system was ripped from your car by a speed bump. That would not be covered by any manufacturer's emissions warranty as it was not a failure of the part. Now your cats are missing, so you replaced them. Seems simple to me But it still would not be legal to relocate them, not that it matters because there are only 1-5 states in this country that would even check for that, and in those states I'm sure hobbyists have found ways around that.

Furthermore, don't waste your time worrying about relocating cats being aganist federal law, because in reality any mod you do to your motor or trans that can effect emissions is illegal. Do a web search on the Clean Air Act, the federal tampering prohibition in section 203(a)(3) of the Clean Air Act (Act), 42 U.S.C. 7522(a)(3). Section 203(a)(3)(A) of the Act prohibits any person from removing or rendering inoperative any device or element of design installed on or in any motor vehicle in compliance with regulations under Title II of the Act (i.e., regulations requiring certification that vehicles meet federal emissions standards). This is by no means limited to exhaust modifications. It's anything you do to change the way air/fuel flows through your motor, or to effect gas mileage. However, this whole law is a waste of time because the feds really have no way of enforcing it once cars make it to the private consumer level.

So long as you can pass whatever state inspection you have to deal with, you have nothing to worry about.

i thought you were allowed to relocate your cats after 3 years or 50k?i thought LTs were legal as long as you keep all emissions equipment intact.

As far as replacing broken cats... Someone sabotaged mine, I do not wish to press charges for property damage.
