Does this bolt directly to my factory catalytic converter?

Yes. This catback system connects at the factory cat converter mounting point and uses the stock mounting brackets. No welding or additional fabrication needed.

Will this system fit with a custom intake or tune?

This is a catback exhaust only, so it works independently of intake or tune modifications. Just confirm your catalytic converter is stock or similarly sized at the connection point.

Do I need to prep or paint this before installation?

No. Stainless steel arrives ready to install — no primer or paint needed. The burnt-tip finish is permanent and requires no maintenance beyond occasional cleaning.
