The damn cat is not doing a good enough job I guess, I get a check engine light every two weeks or so. And when I hook up the machine it tells me catalist somthing or another. I might as well have just put a testpipe on..

I don't think that's (the RT Cat) the problem.. I've had mine for over a year now... and that's the only one I have... you've got the precats too...

Connections or perhaps rear sensor?

I have a Stillen y-pipe with catback and the R/T cat. I changed my rear o2 when I put the exhaust on. I also run a 40"shot" of NOS. No leaded race gas or fuel additive. Maybe an o2 is going south.
