aFe MACHForce XP 4in DPF-Back Stainless Steel Exhaust for 2007-2010 GM Silverado/Sierra (V8-6.6L)

Fits 2007-2010 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models equipped with the V8-6.6L LMM Duramax diesel engine.

The aFe MACHForce XP DPF-back exhaust system is engineered to optimize exhaust flow and lower exhaust gas temperatures (EGTs) on your heavy-duty GM truck. Constructed from 4-inch mandrel-bent 409 stainless steel tubing, this system provides a significant upgrade over restrictive factory piping. The 24-inch long high-flow muffler is specifically designed to absorb high-pitched tones while maintaining a powerful, deep exhaust note without sacrificing performance.

Installation is a direct bolt-on process using factory mounting locations. The system features heavy-duty OE-style bayonet hangers and a high-quality flange to ensure the pipes remain stable even under high-vibration and high-heat conditions. A polished, intercooled tip provides a clean finish and helps manage heat at the exit point.
