In testing, the cat-back exhaust system resulted in gains up to +6 horsepower and +11 lbs. x ft. of torque, as measured on our in-house dyno (tested on 2008 Toyota FJ Cruiser V6-4.0L)
aFe power introduces the Hi-Tuck "Rock Basher" (RB) Cat-Back Exhaust System for 2007-2014 Toyota FJ Cruiser with V6-4.0L engines. This cat-back exhaust system is constructed of 3" 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 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.
Flow and Performance:
This MACH Force-Xp cat-back exhaust system is constructed of 3" mandrel-bent, 409 stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response.
Stainless Steel Muffler:
This system incorporates a high flow, stainless steel performance muffler used to provide a deep, throaty, powerful sound on acceleration but maintain a smooth sound at idle.
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.
Note: Removal of the skid plate required for TRD models
All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
