• Up to +9 horsepower and +8 lb-ft of torque gains verified on aFe’s in-house dyno
• Hi-Tuck tip design for increased ground clearance during extreme off-road maneuvers
• 2-1/2" mandrel-bent tubing made from 409 stainless steel for superior strength and corrosion resistance
• 6" round by 14" length high-flow stainless steel muffler for reduced exhaust restriction and a deep, low exhaust tone
• 100% hand MIG-welded construction ensuring durability and long-lasting performance
• Factory-style bayonet hangers and ball flange connection for a secure, factory-like fit
• Includes all necessary hardware for a straightforward, bolt-on installation
• Compatible with both 2-door and 4-door Jeep Wrangler JL models

Construction & Design

The Force-Xp Hi-Tuck exhaust is crafted from premium 409 stainless steel tubing, chosen for its excellent balance of strength, heat resistance, and corrosion protection. The 2-1/2" mandrel-bent pipes maintain consistent diameter throughout bends, optimizing exhaust flow and minimizing turbulence. Each weld is performed by hand using MIG welding techniques, ensuring robust joints that withstand the rigors of off-road use.

The Hi-Tuck design positions the exhaust tip higher than conventional systems, reducing the risk of damage from rocks, debris, and uneven terrain. This thoughtful engineering not only protects your investment but also enhances your Jeep’s off-road capability by improving clearance angles.

Performance & Sound

Engineered to boost your Jeep’s performance, this cat-back exhaust system delivers measurable gains of up to +9 horsepower and +8 lb-ft of torque. These improvements translate into better throttle response, increased mid-range power, and enhanced overall driving dynamics.

The high-flow muffler design reduces restrictive backpressure while absorbing high-pitched frequencies, resulting in a deep, aggressive exhaust note that is both noticeable and refined. This sound profile complements the Jeep’s rugged character without being overly loud or intrusive.

Installation & Fitment

The aFe MACH Force-Xp Hi-Tuck Cat-Back Exhaust is designed for a direct bolt-on installation using all factory mounting points. It features factory-style bayonet hangers and a ball flange connection, allowing for a secure fit without the need for cutting, welding, or additional modifications. This system fits both 2-door and 4-door Jeep Wrangler JL models equipped with the 3.6L V6 engine from 2018 through 2020.
