well one of them is in the stock position, its just that i have another cat on the other side. I believe this only works for 95 and earlier because 2 cats were mandated in 96. Anyway it works for me. I'm planning on some head work , most likely from LE, and i bet it still won't put me close.

Bottom line putting a cam in you car in an emissions state is a risk. It may not work. Just have a plan B. Ask everyone if they know a "friendly" shop that will pass you anyway. Research tricks to get you around the test if things go wrong...ethanol in the tank..special tunes...temporary extra cats...etc. Just buy one that you think will pass and go for it.

I have passed our tests with a cc305 and an LE1 emissions cam both with a madz28 tune. I would imagine a hotcam or others similar will have no problem
