Why 304 Stainless Steel?

304 stainless steel is the industry standard for performance exhaust components, offering excellent resistance to heat, oxidation, and corrosion. Unlike mild steel hangers that rust and fatigue over time — particularly in the harsh under-vehicle environment — the UNB020/SS maintains its structural integrity and appearance through years of heat cycling, road exposure, and vibration. The 8mm rod diameter provides a robust, rigid support point suitable for both light and heavy exhaust systems.

Universal fitment — suitable for any vehicle when making custom exhausts. Sold as a kit. Always use appropriate rubber exhaust mounts or isolators to allow for thermal expansion and vibration dampening.
