a cat-back is from "the cat back" it is only a Y pipe and muffler or just a pipe and a muffler.

yeah, like Santiago said, the part of the exhaust that is behind the CAT (ie from the pipe coming off the cat to and including the mufflers).

Your doing fine.

A cat-back system is only an upgrade of the components that bolt up behind your stock cat. So a cat-back is the y-pipe and the two mufflers. A full system on a TII has a downpipe from the turbo, then the pre-silencer, then the Y and then the mufflers. The full system I describe above is called a turbo-back system.

Your other option to stay emissions legal is to get a high-flow performace cat.
