Finish off the system with a 5" diameter mirror polished exhaust tip.(optional) Lower EGT (exhaust gas temperature), improved fuel economy along with more towing power are just some of the added benefits of having this system installer on the Duramax.

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.
