Do I need special fasteners or clamps to install this?

Installation hardware for connection at the cat is not specified. Verify bolt pattern at the factory Cat flange before ordering — you may need to source hardware separately or reuse OEM fasteners if compatible.

Will the stainless steel tip tarnish or need polishing?

Stainless steel naturally oxidizes slightly but resists heavy rust. Regular wash-downs keep it bright; polishing compound maintains shine if desired. It won't degrade like mild steel.

Is this a straight bolt-on, or does it require welding?

Catback systems bolt at the catalytic converter — no welding. Route the system along the factory path and secure with clamps and fasteners at the cat connection and bracket points.
