The MagnaFlow 2007-2008 Chevrolet Avalanche Street Series Cat-Back Performance Exhaust System brings out the personality of your 5.3L 2007-2008 Chevrolet Avalanche with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 3in. main piping and 1 Straight-Through mufflers ending in a Single Passenger Side Rear exit with 5.5in. Polished Welded-On Double Wall Straight Cut Rolled Edge tips, this Chevrolet Avalanche 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 Chevrolet Avalanche'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 16721 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. 16721 is produced using CNC precision robotic manufacturing techniques and is backed by MagnaFlow's 1-year limited finish warranty and limited lifetime construction warranty.
