Cat-Back Exhaust

The Hi-Tuck "Rock Basher" Cat-Back Exhaust System is constructed of 2-1/2" mandrel-bent stainless 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 also comes complete with a 14" length high-flow straight through designed muffler to absorb high pitch tones producing a powerful sound. All necessary hardware is included for a hassle-free installation. This unit fits with most after market Evap skid plates. This MACH Force-Xp cat-back exhaust system is constructed of 2-1/2" mandrel-bent, 409 stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response. This system incorporates a high flow 14" length muffler for an aggressive sound. The muffler is located prior to the rear axle for increased climbing angles. This system may have a slight drone in some applications due to the short muffler. 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. 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 that does not change with time. The 409 stainless steel performance muffler is designed to provide a deep, throaty, powerful sound on acceleration but maintain a smooth sound at idle. The driver-side exit location is perfect for adding 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 (46-79001)

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
