Found this thread because I was searching for the name of the company I bought my cat from (Jayracing) and just thought I'd throw in that the one I bought a few years ago is still holding strong. I'll admit that my SVT has been off the road for a while, but for the year (or so) of road time it had with this cat, it was fine -- and a deal, from what I remember.
Zetec....is that like Vtec or something???
