Re: stuff for 02 gt
well seeing that my cobra just failed miserably with a Bassani Catted Xpipe, and passed with flying colors with the stock Hpipe, id have to say no, you wont pass with anything but stock h-pipe or possibly a aftermarket with 4 cats. only way to pass with a o/r H or X is if you have a hookup or God himself tuned your car.
after seeing the test results of a aftermarket Xpipe compared to a stock Hpipe it blew my mind. I really would never have thought going from 4 cats to 2 high flow ones would make that much of a difference. I assumed it would still be dirty, but basically a catted h/x pipe is just so when you get pulled over and/or a cop looks under the car, he cant fine you the 1,000$ or whatever for no catalytic violation.
