Will I need to remove the factory exhaust to install this?

Yes. You'll unbolt the stock system at the catalytic converter connection point and bolt this catback in its place. Basic hand tools and a jack will get it done—expect 1–2 hours depending on rust.

Do I need special fasteners or clamps to mount this?

The system connects at the converter flange using existing bolt holes. Confirm your truck has all original mounting points before ordering—any damage to the converter flange will complicate fitment.

Does the stainless steel tip come polished or raw?

Stainless steel natural finish is included. Over time it'll develop a light patina; you can polish it if you want shine, but it won't rust.
