Description
The Scorpion 2-1/2" Hi-Tuck Aluminized Steel Cat-Back Exhaust System, also known as the Rock Basher (RB) system, is engineered for Jeep Wrangler JK 2-door and 4-door models (2007–2018) to maximize performance, sound, and off-road clearance. Designed with the Jeep off-roader in mind, the Hi-Tuck system increases horsepower, torque, and throttle response while providing a deep, aggressive exhaust tone.
Constructed from 2-1/2" mandrel-bent aluminized steel tubing, the system features smooth transition bends for unrestricted exhaust flow and reduced turbulence. A 14" 409 stainless steel high-flow muffler delivers an aggressive yet refined sound while minimizing exhaust drone. The muffler is positioned forward of the rear axle for increased off-road climbing angles and to accommodate on-board accessories such as air compressors or skid plates.
The Hi-Tuck tip design enhances ground clearance during extreme climbs and descents, making it ideal for off-road enthusiasts. OE-style bayonet hangers and heavy-duty band clamps ensure a secure, factory-style fit that maintains pipe location under high vibration and heat conditions. The system includes all necessary hardware for hassle-free, direct bolt-on installation and is compatible with most aftermarket EVAP skid plates.
