Exhaust Pipe Kit for Dodge Ram 2500 3500 (2019-2024) 6.7L Turbo Diesel

High-Flow 4-Inch Exhaust Pipe Kit for 2019-2024 Ram 2500, 3500 (6.7L Cummins)

What it Does: Replaces the restrictive factory exhaust section with a 4.0-inch mandrel-bent T-409 stainless steel pipe to lower exhaust gas temperatures (EGTs) and dramatically reduce system backpressure.

The Stock DJ / D2 Ram Weakness

The factory exhaust system on the 6.7L Cummins utilizes crimped sections, dense particulate filters, and restrictive piping diameters that heavily bottleneck exhaust gas velocity. Under heavy towing or sustained load, this OEM configuration traps excessive heat, leading to elevated EGTs and localized thermal soak. This heat stress reduces overall engine efficiency, forces the variable geometry turbocharger (VGT) to work harder to evacuate spent gases, and limits the powertrain's potential during high-load applications.

The Engineering Solution

This direct-replacement exhaust pipe eliminates factory bottlenecks by utilizing 4.0-inch mandrel-bent T-409 stainless steel tubing. The constant-radius bends prevent internal turbulence and maintain steady exhaust gas velocity throughout the system. Engineered without sensor bungs for a streamlined off-road configuration, the kit features a CNC-machined flange equipped with deep-penetration precision TIG welds. This ensures structural rigidity and a leak-free seal under extreme thermal expansion cycles. By significantly reducing backpressure, this setup allows the 6.7L Cummins to spool faster, shed heat efficiently during heavy towing, and produce a deeper, more pronounced diesel exhaust note.
