Construction & Design

The MACH Force-Xp exhaust system is meticulously crafted from premium 409 stainless steel, known for its excellent resistance to rust and corrosion, making it well-suited for off-road and all-weather use. The 2-1/2" mandrel-bent tubing preserves smooth exhaust flow by minimizing restrictions and turbulence. Hand MIG welding throughout the system guarantees robust joints that withstand vibration and thermal expansion over time.

The Hi-Tuck design is a key engineering feature that elevates the exhaust above the frame rail, protecting it from rocks, debris, and rough terrain impacts. This thoughtful placement helps prevent damage during extreme off-road maneuvers while maintaining factory mounting points for a clean, stable installation.

Performance & Sound

With up to 9 horsepower and 8 lb-ft of torque gains, this exhaust system unlocks additional engine performance by reducing backpressure and improving exhaust scavenging. The free-flowing muffler is tuned to produce a deep, aggressive exhaust tone that enhances the driving experience without overwhelming cabin noise. The polished stainless steel tip adds a premium look while allowing for easy removal to increase clearance when navigating tight trails.

Installation & Fitment

The aFe MACH Force-Xp Hi-Tuck Cat-Back Exhaust installs using all factory mounting locations, making the process straightforward and hassle-free. OE-style bayonet hangers secure the exhaust in place, maintaining proper alignment and reducing the risk of rattles or movement under high vibration and heat conditions.
