Sure. Basically, "cat back" means only the rear muffler (and perhaps rear tailpipe sections) are replaced--those pieces after the second catalytic convertors. The function of these pieces, while they may have a small effect on backpressure, is really to control the sound eminating from the car. It cannot be construed, except by those with wild imaginations, as a "performance modification".
