MBRP Armor Pro Series exhaust systems are crafted out of T304 Stainless Steel - the most durable material grade that money can buy. The T304 Stainless Steel tubing is easy to clean and maintain. It’s the obvious choice for you if you operate your vehicle in extreme conditions. 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.
