Re: Which cat converter
get the magna flow universal an exhaust shop weld it in. summit has them pretty cheap and probably $25 to install. stay away from catco, i've had bad luck with them and have heard others having the same problems, but some others have no problems with them. and drive with it installed for at least 100 miles before you attemp to get it smogged, if you have the sniffer test.

Re: Which cat converter
Magnaflow, Catco, and Random Technology all make good "high-flow" cats.
Thank you for keeping your car smog-legal and keeping the cat on it.
