I got a response that suggested that I use a hi-flow Cat.... I talked to a mech about it, and he told me that even if was able to find one it may just work fine for a short period of time.... but eventually I would get a check engine light because the computer wouldn't read something right or whatever.

Man, I'm feeling real ignorant on this subject!!!! I know that there has GOT to be a less expensive solution to this friggin' CAT problem! It's just a catalytic converter! Not a transmission!!!!!!!!
