All 50 states. Emissions standards that relate to catalytic converters are federal, not state.

Google search for: long tube headers legal

First 3 results:

Nothing, even if it's catted, with long tube headers is emissions legal in any state.

From a legal standpoint no long tube headers is "legal" for on-road use if it removes or moves the factory cat.

What is the deal with long tube headers and passing emissions? ... They are not legal under any circumstances on a daily driven car.

Thanks for that info. Knew removing it was illegal, but thought as long as you left it on you were okay. Had considered it for mine. That just shot that idea all to 7734.

i havent seen or heared of a law stating that u can not move the cats from the factory location. so if u have i would like to c a link to the site and if ur state isnt emission controlled meaning u have to get it checked every year to get new tags then i wouldnt worry get them put them on and disturb the peace lol if ur truck has to have cats on it because the o2 sensor is after it u can buy high flows or i cant remember who makes them but they are liar o2 sensors that sends the proper readings to the computer

Don't know myself. Do know smog laws are FEDERAL as he stated in his post. Think I'll try Google like he said to see what comes up.

depends on where you live in Tennessee. in Memphis they do have inspections, but only in the city limits. not sure about the other big cities.

The interpretation of smog laws is where things get stupid, I mean why does it matter what components are on a vehicle or where they are positioned as long as the tailpipe emissions are within spec? Isn't that what it's all about?

I have Pace Setter short headers that I put on originally with my stock exhaust, didn't see much change then. A year later I put full front to back duals on. 2 1/2 inch to the mufflers, 2 1/4 inch tail pipes. Big change in the power and sound.

Did the exact same mod to my last truck, excluding tailpipe. Night and day difference. My current truck is basically the same beast as before, and she is slow compared to the old truck with headers and duals

Edit: Oh wait, nevermind. I had LT headers

So you're still running the pacesetter shorties? You just ran a true dual exhaust all the way back? Do you still have the cats? What did you do with the o2 sensor?

Tried Google, can't find an official government place that says anything. Not sure what to look for. Found what AndyM said, that's what somebody said on a Mustang site. Also a corvette ( piece of 4starsrolet ) site below that said the same thing. Anybody know where to find the " official " government answer? I like the idea of real headers & true duals, but want to stay legal. Just thought of something I didn't try Googleing. May be back to edit this in a few minutes.

Here: http://www.epa.gov/otaq/cert/factshts/catcvrts.pdf

Section 8, paragraph 5.

(5) Install the converter in the same location as the original.

Okay, found it. Here are two links to read. Sounds like you're pretty much stuck with " what ya brung ".

Catalytic Converter Laws

http://www.epa.gov/OTAQ/cert/factshts/catcvrts.pdf

Second one is from the E.P.A. & the " Official " government site. Not good news .
