catless......lost my kitty.
its doable, maybe. it all depends on who looks at your car, if you have a cel light on, and how clean it runs.
you probably won't run clean enough, but if you are able to you could probably pass. take the bulb on the check engine light out (or does it come on the dic?). as far as the visual, most people working at emissions places don't care much about anything. I have passed with a piece of sheet metal bent over a straight pipe where the cat should have been. most people would look under the car, see the resonator and figure its likely the cat.
all depends on where you live though.
get a cat and make life easy. dealing with those A-holes once a year is more than enough.

current setup injen cai and corsa sport cat-back. with a pacesetter header and the CA down pipe w/ cat will i still pass?
I've been talking with a local shop w' dyno thats familiar with smt-6. he's confident he can tune the balt. not looking to go nuts on the power i just want to squeeze maybe 20 more serious ponies out after all is said and done and still get my gas mileage.

This is really simple. There is no mystery here in Illinois. If you want to see for yourself, go to vehicle emmisions test facility and see what they do.
They will put your car on a dyno, hook it to an OBD-2 scanner, stick an O2 sensor in your tailpipe, and run the car. If you have emmisions related codes or their O2 sensor during the dyno run picks up too rich of a mixture, you fail. Plain and simple.
Take out the CEL bulb? Thats a new one.

let me rephrase the question. a higher flowing cat is still going to allow me to pass while at the same time offering up initial gains or the ability to aquire more power then with the stock cat?

That sounds better. As long as you keep a cat that does work well you should be able to pass Illinois emmisions without an issue.
I do know they didn't used to use any computer scanning while testing, but that was before even obd 1, so I guess they wouldn't have a viable way of testing the computer, so they just looked for the bulb, if it didn't come on then all was good. they were suppose to verify that the bulb came on with ignition, but I know many people that passed the test by pulling the bulb. I've heard of some people using a very low amp fuse that would let the bulb come on for a second, then the fuse would pop and it would appear that the just went out like usual, they had it hooked on a switch they would flip as they shut the car off and gave the keys to the guy running the test.
I've known a few people (not that i've ever done it myself...
) that have got some pretty serious race cars through emissions. Barely...
thanks halfcent exactly what i wanted to know.
now instead of starting a new thread i got another question. Will adding the header and CA pipe without fuel management going to hurt or help my performance? I've heard of back pressure but I've also read it doesn't apply to our engines as though it would say a honda.
