I don't know of any websites to where I can find the MRT Catted H besides exhaustworld.com which is too expensive. I also don't know where you guys buy your VRS X pipes. I'd like to know b/c I'm interested in both catted versions possibly to go along with the SLP Loudmouth I'm ordering this week. Or do you think I could get away with doing a true offroad pipe with that exhaust in California. Either way it's illegal in Cali without 4 cats on the midpipe so I guess why have 2 when it's still illegal and just have none. But anyway, where in the hell are you guys purchasing these?
