Product Description

The MBRP S6130409 4" DPF-Back Exhaust System is engineered specifically for Dodge/Ram 2500 and 3500 heavy-duty trucks equipped with the 6.7L Cummins diesel engine from model years 2007 through 2012. Its mandrel-bent 4" tubing and T409 stainless steel construction improve exhaust flow and reduce backpressure compared to the stock setup, which can help lower exhaust gas temperatures and unlock additional torque and horsepower potential. Tour-profile tuning delivers a deeper and commanding exhaust tone without excessive cabin drone.

This DPF-back system bolts on using existing factory hangers and includes a polished 5" stainless steel tip for an aggressive appearance behind your truck. Designed for lasting performance and backed by a lifetime warranty, the S6130409 is ideal for diesel truck owners who want a quality performance exhaust that enhances both sound and flow while retaining emissions-compliant hardware.

Fitment is confirmed for 2007-2012 Dodge/Ram 2500 and 3500 trucks with the 6.7L Cummins engine. Always confirm your specific exhaust layout and emissions equipment before purchase.
