Whats the best/affordable high-flow cat for a ws6?

[Mudvayne24]

Hey guys. I have an 02 WS6 running SLP headers into a borla catback, but my cats are completely shelled. Needless to say, my inspection's been up since Dec. 2008 (Yes, i'm good at not getting caught haha). Not only that, but it's my daily driver and I'm tired of breathing in fumes all day long. Welding is not a problem. I still have my 02 sensors in the pipes, so I just need something to be able to slap in there so I can erase the code. Cheaper the better as long as it's decent quality (my stock ones burnt out from the extra SLP flow and heat). Thanks guys!
