Why Choose Stainless Steel? SS304 stainless steel offers superior longevity compared to mild steel exhaust components. It resists rust and corrosion from moisture and acidic exhaust gases, maintains structural integrity at high temperatures, and won't deteriorate over time like coated mild steel. This means your custom exhaust will look better and last longer.

Fabrication Benefits: The raw finish welds cleanly with standard TIG or MIG equipment, the smooth transitions minimize back pressure, the consistent wall thickness ensures strong, leak-free joints, and the corrosion resistance eliminates the need for protective coatings in most applications.

Pro Tip: Pair with Proflow's oval and round exhaust tubing (sold separately) for a complete stainless steel exhaust system that delivers both performance and longevity.
