Description
The aFe POWER MACH Force-XP 3" Cat-Back Exhaust System is engineered to deliver proven performance gains, aggressive sound, and OE-quality fitment for 2004–2007 Chevrolet Silverado 1500 and GMC Sierra 1500 gas trucks. Designed to fit both V6 and V8 engines, this system produces up to 9 horsepower and 15 lb-ft of torque at the wheels, making it a powerful upgrade over the restrictive factory exhaust.
Constructed from 3-inch mandrel-bent 409 stainless steel tubing, the MACH Force-XP exhaust maintains consistent pipe diameter throughout the system, allowing exhaust gases to flow smoothly with minimal turbulence. The increased diameter and smooth transition bends help eliminate horsepower-robbing backpressure, improving throttle response, horsepower, and torque across the RPM range.
A straight-through, free-flowing stainless steel muffler is used to absorb unwanted high-pitch tones while delivering a deep, aggressive exhaust note under acceleration. This design maximizes exhaust flow without sacrificing sound quality or daily drivability.
For long-term durability and precise fitment, the system utilizes OE-style bayonet hangers, ensuring proper exhaust alignment during high heat and vibration conditions. High-quality OE-style flanges and stainless steel band clamps provide a complete 360-degree sealing surface to prevent leaks and maintain consistent performance.
Installation is fast and hassle-free, as the system uses all factory mounting locations and includes all necessary hardware. The exhaust is finished with a bold black 304 stainless steel rolled, slash-cut tip, adding an aggressive visual upgrade to match its performance gains.
Proudly engineered and manufactured in Corona, California, the aFe POWER MACH Force-XP Cat-Back Exhaust System delivers the ideal balance of performance, sound, fit, and value.
