Construction & Design

The exhaust system is built using premium 409 stainless steel tubing, known for its excellent resistance to rust and corrosion, making it ideal for off-road and all-weather use. The 2-1/2" mandrel-bent pipes maintain consistent diameter throughout bends, promoting unrestricted exhaust flow and maximizing performance gains.

Each component is hand MIG-welded to guarantee long-lasting durability and structural integrity, even under the demanding conditions of off-road driving. The Hi-Tuck tip is uniquely engineered to tuck the exhaust outlet higher than conventional designs, providing increased ground clearance and reducing the risk of damage during trail excursions.

Performance & Sound

The aFe MACH Force-Xp Hi-Tuck Cat-Back Exhaust delivers measurable performance improvements with a gain of up to 9 horsepower and 8 lb-ft of torque, enhancing throttle response and overall engine efficiency. The free-flowing muffler design minimizes restrictive backpressure while absorbing undesirable high-frequency tones, resulting in a deep, aggressive exhaust note that enhances the Jeep’s muscular character without being overly loud or droning.

Installation & Fitment

Installation is straightforward and designed to be a direct bolt-on upgrade using all factory mounting locations. This ensures a secure fit and eliminates the need for cutting, welding, or additional modifications. The OE-style bayonet hangers and high-quality band clamps provide a leak-free seal and maintain pipe stability, even under high vibration and heat conditions.

Please note this exhaust system is compatible only with 4-door Jeep Wrangler JL models equipped with the 3.6L V6 engine from model years 2018 through 2021.
