The Duramax has a refined toughness to it. MBRP Inc. Has left the refined part to General Motors, and added extra toughness.

Turbo Back
Turbo Back Kits mount directly to a turbo and provide maximum diameter with reduced band degree angles and mandrel-bent pipe. The objective is to minimize exhaust gas temperatures while optimizing exhaust flow, torque, and horsepower.

Downpipe Back
Ideal for off-road applications, Downpipe Back Kits mount to the stock short downpipe in Duramax-equipped trucks, eliminating the catalytic converter. Their objective is the same as Turbo Back Kits.

Filter Back
The new generation of diesel vehicles has diesel particulate filters and a range of sophisticated emissions-control components. This requires a new approach to gaining power and efficiency without jeopardizing safety or voiding vehicle warranties. MBRP is first with the filter back solution.

NOTE: This product CAN NOT ship to California due to CARB regulations.
