First, welcome to CEG!
Second, there are a few different applications running around. There are three Zetecers running around w/ SVT exhausts (I'm destined to be #4 - it's in my garage, but I'm waiting to have it done). Also, I think a few have kept the stock piping, but changed resonators/mufflers. I currently have the stock exhaust w/out the resonator. I like it - it's cheap and quick to do.
One suggestion I have is to use the 'Search' feature at the top of the page. Make sure you keep your search limited to the Zetec forum at first. The exhaust topic has been discussed many, many times and you'll probably find some excellent beginner's info in there.
Good luck...
