Construction & Design

The MACH Force-Xp Hi-Tuck Axle-Back Exhaust is crafted from premium 409 stainless steel tubing, known for its excellent corrosion resistance and strength. The 2.5-inch tubing is mandrel bent to maintain consistent diameter throughout bends, minimizing flow restrictions and maximizing exhaust efficiency. Each weld is hand-crafted using MIG welding techniques, providing race-proven durability and a clean, precise finish.

The Hi-Tuck tip design elevates the exhaust outlet, offering additional clearance to prevent damage from rocks, debris, or uneven terrain encountered during off-road driving. OE-style bayonet hangers secure the system firmly in place, reducing movement and wear over time even under high vibration and heat conditions.

Performance & Sound

This axle-back system enhances your Jeep Wrangler’s performance by improving exhaust flow, which can lead to increased horsepower, torque, and throttle response. By replacing the restrictive stock muffler with a more free-flowing design, the system unleashes a deeper, more aggressive exhaust note that complements the rugged character of the Wrangler without being overly loud or intrusive.

Installation & Fitment

The aFe MACH Force-Xp Hi-Tuck Axle-Back Exhaust is designed for a direct bolt-on installation using all factory mounting points, making the upgrade quick and straightforward. No cutting, welding, or modifications are required, and the system fits both 2-door and 4-door Jeep Wrangler JL models from 2018 through 2020 with 2.0L turbo or 3.6L V6 engines.
