Do I need any hardware or hangers to install these pipes?

Hangers, clamps, and adapters are not included with this kit. You'll source those separately based on your engine bay layout and muffler choice. Measure twice before welding anything in place.

Can I use these pipes as-is, or do they need prep before welding?

They're raw stainless sections. Wipe them clean of any mill residue before you cut or weld. No primer or coating is applied — they're ready to fabricate.

What happens if a section cracks or splits after I build with it?

Once you've welded and installed these, they're part of your custom build. Stainless resists corrosion but is not bulletproof against cracks from poor welds or impact. Inspect your welds closely before final assembly.
