Description
The aFe POWER MACH Force-Xp 3" Stainless Steel Cat-Back Exhaust System delivers measurable horsepower and torque gains while producing an aggressive, high-performance exhaust note. Designed for 2009–2019 Chevrolet Silverado and GMC Sierra 1500 trucks equipped with V6-4.3L, V8-4.8L, or V8-5.3L engines, this cat-back exhaust is engineered for maximum flow, durability, and performance.
Constructed from 3" 100% MIG-welded, mandrel-bent stainless steel tubing, the MACH Force-Xp system minimizes turbulence while maintaining a smooth airflow path for enhanced throttle response. The included single-in, dual-out free-flow muffler optimizes performance across the entire power band while producing a deep, aggressive tone. Dyno testing on a 2014 Chevrolet Silverado V8-5.3L confirmed gains of up to +14 horsepower and +17 lbs. x ft. torque.
Finishing Touches: Dual 4-1/2" polished stainless steel side-exit tips with laser-cut aFe POWER badges give the truck a standout, aggressive appearance. The tips are designed to provide a factory-style fit while visually enhancing your vehicle.
