Product Description
DIAMOND EYE K5244A-RP is a 5" aluminized steel cat-back exhaust system engineered for the 2004.5–2007.5 Dodge Ram 2500/3500 with the 5.9L Cummins. This “-RP” configuration deletes the muffler (straight-pipe) and uses split-side tailpipe hardware to run single or dual exit as configured during install. Designed for free-flowing exhaust, lower backpressure, and a classic turbo whistle under load.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you have a 2004.5, 2005, 2006, or early 2007 (2007.5 body with 5.9L) Ram 2500/3500 5.9L Cummins (all cab & bed lengths), this system is built for that application. Always confirm your model year split (2004.5+) before ordering.
FAQ: WHAT’S THE DIFFERENCE BETWEEN K5244A AND K5244A-RP?
K5244A is the standard 5" aluminized cat-back with a muffler; K5244A-RP replaces the muffler with a straight “replacement pipe” for maximum sound and flow.
FAQ: IS IT LEGAL IN MY STATE?
Because this is a muffler-delete straight pipe, some retailers flag shipping restrictions to certain states. Check your local regulations; many sellers list no shipping to CA, CO, or NY for this kit.
