MACH Force-Xp 3" 409 Stainless Steel Cat-Back Exhaust System – Chevrolet Silverado & GMC Sierra 1500 (2009–2019)
Take your truck’s performance and style to the next level with the MACH Force-Xp 3" 409 Stainless Steel Cat-Back Exhaust System by aFe POWER. Designed for the 2009–2019 Chevrolet Silverado 1500 and GMC Sierra 1500 with V6-4.3L, V8-4.8L, and V8-5.3L engines, this exhaust system delivers significant horsepower and torque gains while producing a bold, aggressive exhaust note.
Precision Engineered for Maximum Performance
Constructed from 3" 100% MIG-welded, mandrel-bent stainless steel tubing, this cat-back system ensures maximum exhaust flow, long-lasting durability, and corrosion resistance. The smooth transition bends reduce turbulence, improving throttle response, horsepower, and torque. In in-house dyno testing on a 2014 Silverado V8-5.3L, this system produced gains of up to +14 HP and +17 lb-ft of torque.
High-Flow Muffler for Aggressive Sound
The system features a straight-through, free-flowing stainless steel muffler, engineered to absorb high-pitched tones and produce a deep, performance-oriented exhaust note while maintaining excellent flow across the power band.
