Filter Back: A Different Kind of 5"
With the advanced technology built into the new generation of Dodge diesel pick-up, a new kind of performance exhaust was needed. MBRPinc has met that challenge with its filter back exhaust systems for the new 6.7L Cummins. The 6.7L’s state of the art emissions control system is built around its diesel particulate filter (DPF), which is designed to dramatically reduce the diesel soot escaping into the environment. Unfortunately, removal of the DPF is not an option. Instead, we have been able to take advantage of the noise attenuation effect of the DPF and dispensed with the stock muffler entirely. We have also been able to dramatically reduce the bend degree angles over the stock exhaust for a faster flowing exhaust and cleaner operating engine.
Then we increased the exhaust volume with a five inch diameter pipe and have gained back some of that classic diesel sound. Add to that some classic MBRPinc styling and you have an exhaust system that is bound to attract attention
