Will this bolt straight onto my stock exhaust?

Yes. This catback system connects at the factory connection point where your original muffler bolts on. No welding or modifications to your existing piping needed.

Do I need to prep or paint this before installation?

No prep required. Stainless steel is ready to install as-is and won't need painting. It'll age naturally with a polished or brushed finish depending on driving conditions.

What mounting hardware comes with this?

The system uses your factory hangers and mounting points. Bring basic hand tools and work in a safe, level area. Refer to your vehicle service manual for any torque specs on fasteners.
