Mach Force XP GM Cat-Back Exhaust

 aFe Power’s newest cat-back exhaust fits  2004-07 GM Silverado/Sierras, both V6 and V8 models.

In recent testing, this exhaust system produced 9hp and 15lbs. x ft. torque at the wheels.

The cat-back design is constructed using 3″ mandrel-bent 409 stainless steel and uses a free-flowing muffler, OE style bayonet hangers, band clamps and all hardware necessary for a hassle-free installation.

The smooth curves and increased diameter of the exhaust system helps remove performance restrictions and keeps exhaust gas flowing smoothly for increased horsepower and torque.

The system is finished off with a black 304 stainless steel, rolled slash cut tip.
