The MagnaFlow Off-Road Pro Series Cat-Back Performance Exhaust System 17146 brings additional off-roading prowess and our deep signature exhaust note to your Truck with a weight-optimized, dyno-tested, corrosion resistant and durable stainless steel design engineered to closely hug the undercarriage for improved ground clearance. Exhaust kit 17146 is engineered to produce Very Aggressive exterior and Aggressive interior sound levels. Extensive 3D scanning was used during the development of this Truck exhaust system to create a direct-fit design, enabling a do-it-yourself installation process. 17146's emissions-legal cat-back design replaces all your truck's exhaust components from the catalytic converter on back with its 3in. diameter mandrel bent main piping that passes through 1 Straight-Through mufflers before ending in a turndown before rear axle exit with 3in. Satin Clamp-On Single Wall Turndown Cut Edge tips. Exhaust system 17146 is produced using advanced CNC precision robotic manufacturing techniques and backed by MagnaFlow's limited lifetime warranty.
