Where can I find information on what will pass and what will not? There is no inspection where I live now, but I have to move for school. I know for a fact the exhaust I have will have to go, but I need help knowing what I can get to replace it. I have never had to worry about it, so it's all new to me.

the states DMV site should give you an idea of what you need to make it pass, and if not, the testing center certainly will.

i would find a stock h-pipe and swap it out until you pass emissions, then put your other pipe back on and release a couple cans of aerosol into the atmosphere to pay the state back for the 10 minutes of bull**** that they made you take to swap exhausts. works every time :nice: :nice:

The only problem with that is the guy before me put in a custom 1 piece from the headers back. He didn't do a very good job.:notnice:
 
Ha, i saw that once. Buddy got a custom exhaust from headers back with flows and tailpipes on.

5 months later we needed to drop the trans, and discovered it was all 1 peice :(



As for requirements, you need cats, mufflers and tailpipes must extend past passenger compartment. (hatch is considered passenger compartment)

As for noise level depends on the state

as for actually passing emmissions also depends on the state. Here in MA, pre-OBD cars no longer need to pass the sniffer...but still need to have cats.

You need cats period..even if your state doesn't inspect.

I have a GT and with most GTs the pipes turndown and are pretty much hidden by the rear bumber cover. Would that pass?

How is the noise level tested? Is it just at idle or do they rev it?

I know I "need" cats, but I didn't put the exhaust in. I would like to put a new system in, including headers, and I will get cats reguardless of where I have to go. Do the aftermarket high flow cats flow better than the OE cats?

Is there anything else I need to worry about?
 
GT turndowns are legal. No need to worry about that. Basically turndowns before the axle usually fail.

High flow cats are legal and do flow better.
