it looks mutch better than the factory one, but does it require the slp cat adapter aswell to hookup the cat? if so is there a part number for this ? does it really make a difrence in the car?

Anybody want to try a GP on that factory replacement? I have been thinking about ordering myself. It sure looks like it would flow alot better.
