Have MPE but why would you want to do this? You'll have to reinstall the cats every year for emissions test and it DOES stink. I had some jackass in a cat-less Camaro ripping around work parking lot and the exhaust stink was nasty. It's also really f'ing bad for you.
Is that worth the what, 20hp you might gain?
