Header Options to Meet Calif Smog I want to know if all headers, long tubes or shorties with cat is consider smog legal. I never see anyone brand that has a OE CARB #? or state that they are 50 States legal. I only see with cats, AIR, etc and Off Road Use Only. But still no advertised OE CARB #.
Thanks!

Hooker, JBA shorties are supposed to be smog legal as they bolt up to stock head pipes/cats. However, most shorties only give about 12rwhp. So, are they worth it??
Hooker has the best price at around $250-270.

ANY full length header, with cats and all the emissions stuff, i.e. egr tube and air tube will pass inspections as far as i know and is legal. my car blows 190 hc's with no cats, egr or air. and that passes, legal limit is 220 so i would imagine if the exhasut was legal it would be no problem
Passing the emissions part is not the problem. Its the visual part where Longtubes or basically anything shiny under car. Thats the problem. I'm in cali so I best find myself a "honest" smog shop lol.
Anything that relocates the cats, that means all long-tube headers, is illegal in California and the rest of the states as well since it is a federal law. Now what you can get away with, that is another story and may vary from state to state and even with counties and different emissions stations. Most people get away with using long tube headers in most areas including California as long as they have some traditional looking cats, not those tube things. Headers aren't really obvious on an LS1 Fbody. But you may still run into a hard-nosed inspector here and there and have to go somewhere else.

carb stickers are quite expensive. Many many years ago i looked into getting one for a chip. They wanted $25K for a single chip for a single car. For testing,documentation, etc. Was easier to sell parts "for off road use only" obviously since this was a low volume product i was/am making for vw's.

Thanks everyone for your responses... I'll look into the JBA or the Hookers and see how they are... any complaints or praise on either one of them?
LS1MONSTER - I'm in Monterey Park... pretty local to you ... maybe we can meet up so I can check out your SLP LTs and see how LOUD they are with our LM?
sscam68 - Great! I'll definately check them out! Thanks!

Hey JRP, when do you have to go in for emissions? When you do let me know what happen so I will know what route to go. I cant wait to get LTs but am putting it off because of emissions. Would cam give you any problems with passing?

im not to worried about the LT's unless i have to go to one of those state inspection places where they check for everything. i think some small whole in the wall asian run facility would be able to overlook them
Yes, cam's often times give you problems passing, especially if they do the sniffer test. If only the OBD2 plug in test, you might get by just my desensitizing the idle missfire test. The biggest safe bet on a cam is probably a 224/224 on 114 LSA with tuning. Without tuning, better stay with a 218/218 114.

. the 224 114 has been proven to pass smog with minimal tuning here in cali. so i'll use that as a starting point. the 112lsa should pass with good tune.
