As long as you have a cat converter and the o2 sensors properly placed and the other emission control systems in place, you will have no problem.

Since the 2.0L on my car has two cats. One right after the head and one under the car, how would that work since I would be replacing the first cat with the turbo manifold and turbo? I was wondering the same thing. I'm from Vancouver, WA and am most likely going to get moved up there when I come back from Iraq. Louisiana doesn't do emmisions testing so I don't have to worry about it.

The emission system only monitors the one cat (usually the first one). When headers are installed, the 2nd cat can be the one that is monitored if/when the o2 sensors are positioned correctly.

After living 4 minutes from work for almost 4 years now I seriously loath getting stuck in traffic. Thanks for the info on the cats. If I get stationed at Fort Lewis I will be in King county I think.

That's Pierce County, but you're only 10 minutes away from Thurston County if you want to live off base and not worry about emissions.

My car gets driven under heavy load (lotta weight @ low RPM), so I'm sure it'll fail in the next few years.:( I'll just use it as an excuse to get a bigger engine.

However, not ALL of Snohomish County has emissions, depends on the town. Unfortunately my place does.:mad:

Pierce County might be the same way depending on which town you're in.:confused:

most stock systems are clean enough that even if you get rid of the first cat and leave the second your car will still pass a sniffer test. now in cal you would have problems.

not too many problems in California as u might think. it just matters how much your willing to pay and what you plan is to pass it.:D

To get stupidly anal about it as soon as you remove a cat and do not replace it with an equal to stock part. You just broke federal emission laws. The real question is... does your state give a damn? TX even has a law saying the same thing the feds do, but I don't see them pushing it outside of the larger cities. I would go down to where you get the car inspected locally and ask them.
