#74657 Well first of all just make sure your buying a catback which is made for your hatch and is for a B-series.

The exhaust will start from after the cat if it's a cat-back.
Anything starting from your down pipe on your header is called a de-cat, thus eliminating the catalytic convertor.

If your buying the Apexi ws2 it will be bolt on, no welding or cutting should be involved at all.

#74820 No, it will not just bolt on. You will need to have a muffler shop or compitant welder modify it to fit. Its either too short or long. I cant remember which.
