The MagnaFlow Street Series 15789 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 1 Straight-Through mufflers ending in a Single Passenger Side Rear exit with 4in. Polished Welded-Single 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 15789 features a cat-back layout that replaces your ride’s stock exhaust components from near the catalytic converter on back.
