what brand cat can i use to go 2.5" and still not throw an emissions code?
i just want a regular 2.5" cat...not a hollowed out race cat with a hole in it..i need something i can stick an o2 sensor behind and have it still not throw a catalyst effeciency code.
can i use a carsound cat? what other brands can i use?
basically i want to be able to pass emissions legitamately by just dropping in my stock OBD2 ecu and stock injectors and not boosting on the drive to the emissions place.
i know most of you aren't tree huggers and dont care about anything but 1/4 mile ETs, but my f*cking lungs quit working when the air gets bad around here, so i wanna be legit.

You can pass emissions w/ a carsound cat, easily. I did it when I had my drag3. General consensus is that carsound flows better than all the other high flow cats.
