The MagnaFlow Street Series 15318 brings out the personality of your Truck with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 4in. main piping and 2 Straight-Through mufflers ending in a Single Passenger Side Rear exit with 5in. Polished Welded-Double Wall-Angle Cut-Rolled Edge tips, this Truck exhaust kit has the performance chops to match its sporty sound and appearance. Upgrade your ride to the next level with an exhaust that has the pipes to put other Truck’s to shame. With this system your vehicle will be producing Moderate exterior and Mild interior sound levels while leaving other cars and trucks feeling envious at every stoplight. Exhaust kit 15318 features a cat-back layout that replaces your ride’s stock exhaust components from near the catalytic converter on back. Extensive 3D scanning during development has resulted in a direct-fit design that you can easily install yourself. 15318 is produced using CNC precision robotic manufacturing techniques and is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
