aFe power introduces the Hi-Tuck "Rock Basher" (RB) Scorpion cat-back exhaust system for 2007-2018 Jeep Wrangler (JK) 2 and 4 door models. Constructed of 2-1/2" mandrel-bent aluminized steel tubing, the smooth curves and increased diameter of this exhaust system helps remove restriction and keeps exhaust gas flowing smoothly for increased horsepower, torque and throttle response. This exhaust system includes a 14" length, 409 stainless steel, high-flow muffler to absorb high pitch tones producing a powerful sound. All necessary hardware is included for a hassle-free installation. Fits with most aftermarket Evap skid plates. Flow and Performance: Constructed of 2-1/2" mandrel-bent, aluminized steel tubing for maximum flow, performance and value. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response. Forward Muffler Location: This Scorpion Hi-Tuck system incorporates a high flow 14" length muffler for an aggressive sound while eliminating exhaust drone. The muffler is located prior to the rear axle for increased climbing angles. And is perfect for adding an on-board air compressor system to the underside of your Jeep. If you are considering an on-board air compressor kit, you need to use this system. Compatible with aFe Power's Glide Guard (Part Number: 46-79001) Hi-Tuck Tip: This exhaust system is finished off with a Hi-Tuck Tip that is developed to give your Jeep extra clearance during extreme angle climbs or descents. Aggressive Sound: A 409 stainless steel performance muffler is designed to provide a deep, throaty, powerful sound on acceleration but maintain a smooth sound at idle. Perfect Fit: An included extension pipe allows this system to fit both the 2 and 4 door Wranglers without modification. OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit.
