I think so. My friend Tim (18mustangs) just moved back to Iowa, and he mentioned having to put his catted mid-pipe and smog back on.

Now that I think about it, where do you NOT need cats?

the more I think about it..how are they gunna catch you? most of the cops around here have no idea what a catalytic converter even is

 

[CManT1914]

It's not likely that they will catch you on the road (unless a cop pulls you over for your exhaust being too loud, in which case they've been known to do a visual inspection for cats, a lot DO know what they are). But you have to have them for inspection. And inspection stations CERTAINLY know what they are.

Does it mess up your computer/cause the check engine light to go on when you have the noncatted pipes on?

I think it is a law that you must have catalytic converters no matter where you drive, but several states don't inspect cars, so you could be just fine. However, I was told by a dealership they would never work on my car if I put an offroad pipe on it. Oh well, more of a reason to do my own.

Only the newer Mustangs (I think 96 and up) required MIL (Malfunction Indicator Lights) eliminators, the 94-95 Mustangs do not require this. Cats or not, you won't have a light come on from swapping mid-pipes.

Yep, as long as your O2's are installed correctly, you shouldn't get any CEL's.

its on the way

If you put your o2 sensors in the check engine lights wont come on. I just put my h-pipe on a couple of weeks ago, BIG difference in sound too i love it. But if anyone gives you any crap or says anything just say, we all use hairspray dont we? lol

Holy crap! I wish that were the case here in Georgia. It seems like more and more counties are being added. Testing here is pretty strict and does involve a visual inspection. Not that I want to build a nasty car, but it would be nice to be somewhat close to regulation without having to worry if I'm off a little.

Not too bad though. In the end, the only trade-off is that I have to keep my smog pump, 2 cats, and keep my cam pretty mild. I'm planning on a 347 with good head and intake combo, however, the cam should keep things legal. Don't think I could get away with longtubes, so that's a negative too.

Georgia law states that any car over 25 years old are no longer required to be tested for emissions. Great, only 13 years to go.
