Wake Up Your Cummins With The Deep Sound And Pulling Power It Deserves

If you drive a 2010-2012 RAM 2500 or 3500 with the 6.7L Cummins, you already know how capable that truck is, but this MBRP 4 inch DPF back exhaust helps it breathe the way it should have from the factory. The larger 4 inch tubing reduces restriction after the DPF, which translates into stronger throttle response and a noticeable bump in power you can feel when merging or pulling a trailer. MBRP rates this system for gains of up to 18 horsepower and 28 lb ft of torque, giving your truck more confidence under load. Additionally, lower exhaust gas temperatures help support performance and efficiency when you are working the truck hard. The single side exit layout keeps a clean, classic diesel look that fits right at home on a heavy duty RAM. What’s more, the system is specifically tuned to deliver a deep, refined tone that adds presence without overwhelming the cab. It is the kind of upgrade that makes every drive more satisfying, whether you are heading to the jobsite or hooking up for the weekend.

Engineered Aluminized Steel Construction Built For Reliable Daily Performance

Underneath the aggressive sound and added power is a system built with durability in mind. This Performance Series exhaust is constructed from heavy duty aluminized steel, offering excellent corrosion resistance at a value driven price point. The fully sealed tubing is designed to reduce the risk of rust through at the seams, which is a common failure point on lower quality systems. Furthermore, the kit is manufactured to the same core specifications as MBRP’s premium lines, ensuring consistent fitment and structural integrity. Installation is straightforward thanks to the bolt on, no weld design that connects directly to the factory hangers on 2010-2012 RAM 2500 and 3500 6.7L Cummins trucks. All required clamps and hardware are included in the box, so you are not chasing extra parts halfway through the job. Backed by a 1 year warranty, this exhaust delivers a balanced combination of performance, sound, and long term reliability for serious diesel owners.
