Built To Push Performance Beyond Stock Limits

The MBRP S61140409 XP Series Turbo Back Exhaust System is purpose-built to optimize performance on the 2003–2004 Dodge RAM 2500 and 3500 equipped with the 5.9L Cummins. Featuring 5-inch mandrel-bent tubing, this system improves exhaust velocity and reduces backpressure from the turbo all the way to the tailpipe. That translates into cooler exhaust gas temperatures, quicker turbo spool-up, and better fuel efficiency under heavy load. Constructed from T409 stainless steel, it’s designed to withstand exposure to moisture, heat, and road debris without compromising strength. A 6-inch polished T304 tip gives it a clean, aggressive look, while the deep exhaust tone provides an unmistakable presence without being overbearing. This system bolts directly to the factory mounting points and includes all necessary clamps and hardware for a straightforward install. It’s also designed for trucks without emissions components, making it a great fit for off-road or competition builds. If performance, longevity, and sound matter to your build, this system delivers measurable gains where it counts.
