[The Burning Rom]

.....a high flow cat would flow WORSE than having no cat at all! The converter catalyzes the exhaust before sending it into the atmosphere. Basically, it just cleans it up a bit. In my opinion, they are somewhat useless (at least around here), and they can be a fire hazard. I've seen them get so hot that they glow red...which can be a fire hazard if the car is driven in taller grass.

If there is no oxygen sensor BEHIND the converter, then removing it will NOT cause ANY driveability problems..as far as the computer is concerned. Neither my TGP nor my GT have converters. And I have no problems with either car.

As for emissions laws if you city doesn't test it every year or two when you renew the plates then you don't have to worry about it. If a law is ever introduced, I would almost bet any car built or modified before the law is passed (that isn't under emissions warranty anymore) will be grandfathered.
