T304 Stainless steel is optimal for harsh or mild environments, because stainless steel has a lower carbon content and higher amount of chromium, it resists corrosion better.

Performance:
A full exhaust system can significantly improve engine performance, with our exhaust systems all of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine's cylinders, allowing it to produce more power and improve vehicle performance and longevity. For the S6059304 we have also improved your exhausts cooling with our vented tailpipe.
