Description
The aFe POWER MACH Force-XP 3" Cat-Back Exhaust System is engineered to deliver proven performance gains, aggressive sound, and long-lasting durability for 2007–2008 Chevrolet Avalanche, Suburban, and GMC Yukon XL (GMT900) equipped with 5.3L or 6.0L V8 engines.
This high-performance cat-back exhaust system is constructed from 3-inch mandrel-bent 409 stainless steel tubing, designed with smooth transition bends to minimize turbulence and exhaust restriction. In testing, the MACH Force-XP system outflows the factory exhaust by 28% and delivers gains of up to +12 horsepower and +14 lb-ft of torque, improving throttle response and overall engine efficiency.
At the core of the system is a straight-through, free-flowing stainless steel muffler, engineered to absorb unwanted high-pitch tones while producing a deep, aggressive exhaust note under acceleration. The system is finished with a high-luster polished 304 stainless steel rolled, slash-cut exhaust tip, adding a bold, performance-driven appearance.
Designed for a precise, factory-style fit, the MACH Force-XP exhaust utilizes OE-style bayonet hangers, high-quality band clamps, and an OE-style flange to ensure proper alignment, long-term durability, and a complete 360-degree leak-free seal. Installation is fully bolt-on using factory mounting locations, with no cutting or modifications required, and all necessary hardware is included.
Proudly engineered and manufactured in Corona, California, the aFe POWER MACH Force-XP Cat-Back Exhaust System delivers exceptional flow, performance, and sound for full-size GM SUVs.
