AFE MACH Force-XP 3-Inch Dual Exhaust System with Polished Tips; Side Exit (09-13 4.3L Sierra 1500)

Description

Professional Cat-Back. Crisp, ultramodern, and aggressive, the aFe Mach Force XP 3-inch Split Side Exit Cat-Back Exhaust with Polished Tips promises hard-charging power with its gleaming exhaust tips bearing the aFe badge in black. The Mach Force lives up amply to that promise, amping up the engine with dyno-tested +17 torque ft/lbs and +14 horsepower across the whole RPM power band. The smooth flow created by turbulence free mandrel bends and a wide-open muffler expels exhaust 29% more efficiently, relieving backpressure for better performance and throttle response. The aFe XP Cat-Back’s exhaust note is commandingly aggressive, leaving no doubt your 2009-2013 Sierra is boss.

Rust-Resistant Design. The aFe Mach Force Cat-Back is a bolt-on component, designed to be attached with hand tools using bayonet-tip hangers that keep the system positioned exactly despite years of vibrations. USA-made and warranted for 2 years, this cat-back is fabricated out of 3″ T-409 stainless steel tubing, with mandrel bends throughout. The muffler and tips are also stainless – the tips are made from T-304 stainless and feature a black-coated laser-cut aFe badge.
