Description
The aFe Scorpion 2-1/2 IN Aluminized Steel Cat-Back Hi-Tuck Exhaust System—also known as the Scorpion “Rock Basher” (RB)—is engineered to deliver enhanced exhaust flow, aggressive sound, and maximum off-road clearance for Jeep Wrangler JK Unlimited (4-Door) models. Designed with value, durability, and trail performance in mind, this system is ideal for Jeep owners who demand functionality without sacrificing reliability.
Constructed from 2-1/2 inch mandrel-bent aluminized steel tubing, the Scorpion RB system improves exhaust gas flow by reducing restriction, resulting in increased horsepower, torque, and throttle response. The system features an 18-inch, two-layer aluminized steel chambered muffler, engineered to deliver a strong, aggressive exhaust note while minimizing unwanted drone during cruising.
The Hi-Tuck design incorporates a forward-mounted muffler positioned ahead of the rear axle, improving climbing angles and protecting the exhaust during extreme off-road use. Completing the system is a Hi-Tuck exhaust tip, designed to provide additional clearance during steep climbs and descents.
A two-piece configuration ensures a straightforward, bolt-on installation using OE-style bayonet hangers, high-quality band clamps, and all necessary hardware. The driver-side exit location allows easy integration of on-board air compressor systems, making this exhaust a smart choice for serious off-road builds.
Engineered and manufactured in Corona, California, aFe POWER exhaust systems are built to meet high standards of performance, fitment, and durability.
