This material can be a great choice for you if you live in a dry climate that doesn't see much precipitation. 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. The black powder coating features a 1-year warranty against factory defects, and the remaining parts feature an industry leading 3-year warranty. MBRP, Stand out from the crowd with a performance exhaust system that sounds great.
