      The Tuned Cat-Back System. MBRP tunes their Installer Series 3.5 in. Single Side Exit Cat-Back Exhaust for maximum performance and ideal sound. The heavy-gauge aluminized steel construction of the Installer Series resists rust and corrosion. Smooth, mandrel-bent curves ease the escape of exhaust gases while generating the beefy, robust tone that sounds like true power. Combined with an easy, straightforward, no-weld installation, these qualities make the MBRP Installer Series a great buy.

      A Tough as Your Truck. MBRP starts with high-quality aluminized steel tubing. Mandrel bends prevent the kinks and obstructions that impede performance. Using their in-house dyno, MBRP tunes their exhaust systems for each specific application. The result is a proven increase in performance, and a definite improvement in sound. MBRP backs the Installer Series with a 3-year limited warranty.

      Smooth Installation. The kit includes all necessary parts and hardware for installation. This system uses stock hanger locations for an easy installation experience. Just follow the easy step-by-step instructions.
