CB 03-06 HUM H2 SPLIT RR
The MagnaFlow Hummer H2 Street Series 16673 brings out the personality of your 6.0L 2003 to 2006 Hummer H2 with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 3 Inch main piping and 1 Straight-Through mufflers ending in a Dual Split Rear exit with 4 Inch Polished Welded-Double Wall-Angle Cut-Rolled Edge-Resonated tips, this Hummer H2 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 Hummer H2’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 16673 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. 16673 is produced using CNC precision robotic manufacturing techniques.
