Ordering stainless steel piping - QUESTION
what gage do i need? and i want to do rear cats and sign a little waiver for the shop that it's for track use etc. when is the only time i could get busted etc? during inspection basically.. or could a cop give it to me also?
Also, there are high performance cats avilable, to be safe, you should get those, and you will pass smog. With out the cats, your chances of passing smog "legalley" is probablly impossible.
I've also seen people hollow out the cat, this way if a cop does look under your car, you would be covered. But again, smoging it every year is a problem.
I would just go with the high performance cats.
