Construction & Design

This cat-back exhaust system is crafted from premium 409 stainless steel tubing, known for its excellent corrosion resistance and durability under harsh conditions. The 2-1/2" mandrel bends maintain consistent diameter throughout the system, optimizing exhaust flow and reducing backpressure. Each component is hand MIG-welded to ensure strong, precise joints that withstand off-road vibrations and heat cycles.

The Hi-Tuck design elevates the exhaust tip, providing additional clearance for extreme off-road maneuvers, while the removable black powder-coated tip adds a sleek, aggressive appearance. The system uses factory-style bayonet hangers and a ball flange connection, preserving the original mounting points and simplifying installation.

Performance & Sound

Engineered to improve exhaust flow, the aFe MACH Force-Xp Hi-Tuck Cat-Back delivers measurable performance gains, including up to +9 horsepower and +8 lb-ft of torque. The high-flow muffler design minimizes restrictive flow and eliminates high-pitched drone, resulting in a deep, throaty exhaust note that enhances the driving experience without being overpowering.
