Technically by law anything that has to do with air coming into or going out of your engine has to be stock, stock replacment, or a C.A.R.B. (California Air Resources Board) approved part for you vehicle. That's why even the K&N cold air kits come with a C.A.R.B. approval sticker that you have to place in the engine bay area. In theory, if that intake allows more air into the engine, the MAF will detect this and increase fuel to the injectors to maintain proper A/F ratio, and since your potentially burning more fuel than the stock CAT was designed to clean, you would be making more pollution. That's their theory. Now that being said, I have a supercharger on my S-10, and have fabricated the entire intake and exhaust system myself (except the cat & headers) from stainless tubing, and have inspected the truck twice and passed both times. Also since your Jeep is a '96, it has OBDII, so they only check the computer to see if it has any DTC's, if its clean then most likely they will never pop the hood, and you will get your sticker no prob.
