Product Description
DIAMOND EYE K5256A is a 5.0" aluminized-steel DPF-back, single-exit (passenger side) exhaust engineered for the 6.7L Cummins. Mandrel-bent tubing reduces backpressure and improves exhaust tone while retaining factory emissions equipment.
FAQ: WILL THIS FIT MY TRUCK?
Fitment is specific to chassis/suspension. This kit fits 2013 Ram 2500 6.7L Cummins (leaf-spring rear) and 2014 Ram 3500 6.7L Cummins (all cab/bed lengths). It does not fit 2014 Ram 2500 coil-spring rear trucks. Always verify your year/series before ordering.
FAQ: WHAT DOES “DPF-BACK” MEAN?
“DPF-back” replaces exhaust tubing after the Diesel Particulate Filter. No tuning is required, and all factory emissions hardware remains in place.
FAQ: WHAT MATERIAL IS IT?
Aluminized steel for strong corrosion resistance and value. A T409 stainless alternative is available (see Cross-Reference).
