aFe Power Diesel DPF-Back Exhaust System for Chevrolet Colorado (LWN) Duramax Turbo Diesel 2016 - 2021

The aFe Mach Force XP Loop Delete/Y-Pipe combo package is engineered to replace the stock loop section and y-pipe to accommodate long arm travel lift kits that interfere with the OE loop and Y-Pipe. This product is constructed of mandrel bent, 2"/2.5 inch 409 stainless steel tubing for maximum flow and comes with all necessary hardware. Cutting is required. The true merged collector is designed to create a smooth transition of exhaust gases as the two tubes are combined into one. This design increases exhaust velocity and eliminates the possibility of any turbulence that form collectors can cause. If you are going to lift your Jeep, you need to add this product. The OE loop tube on the drivers side comes into contact with aftermarket long arm travel kits. Mandrel bent tubing allows for smooth transitions of exhaust gas increasing exhaust velocity, increasing horsepower, torque and improving throttle response.
