Description
Note: This system will NOT fit on a 2500 Series with air-ride! Requires (3) M10x1.5 40mm bolts and (3) flanged nuts for installation (not included). Ram 2500 uses coil springs, Ram 3500 uses leaf springs.

This high-flow 4" exhaust kit features 16-gauge mandrel-bent T409 stainless steel and a high-flow muffler for optimal diesel performance. Complete with clamps, pre-welded contour hangers, and reinforced flanges, installation is fast and hassle-free. Designed for 6.7L engines, it boosts torque, throttle response, fuel efficiency, and exhaust flow while lowering EGTs for reliable power and sound.
