Do I need clamps or hangers to install this?

Mounting hardware is not included with the kit. You'll need to source clamps, U-bolts, or hanger brackets based on your specific routing and vehicle attachment points. Measure your current setup or consult your exhaust design before ordering fasteners.

Can I weld this piping directly or does it need prep work?

The polished finish will need to be removed at any welding joints. Use a wire wheel or sandpaper to expose bare metal at connection points before welding. The polished surface elsewhere will be unaffected during the process.

What's the return window if the diameter or routing doesn't work for my setup?
