Product Description
DIAMOND EYE K4236A is a 4.0" aluminized steel, cat-back, split-side (dual exit) exhaust system engineered for the 2004.5–2007.5 Dodge Ram 2500/3500 with the 5.9L Cummins. This kit replaces the factory system from the catalytic converter back and uses mandrel bends and a straight-through stainless Diamond Eye muffler for lower EGTs, improved throttle response, and a deeper tone.
FAQ: WILL IT FIT MY TRUCK?
Designed for 2004.5–2007.5 Ram 2500/3500 5.9L Cummins (all cab/bed lengths). If your truck is early-2007, verify build date/emissions configuration to ensure the correct cat position and hanger layout.
FAQ: DOES IT INCLUDE A MUFFLER?
Yes—this K4236A kit includes a Diamond Eye stainless muffler. If you prefer louder sound, the K4236A-RP “no muffler” version is the direct alternative.
FAQ: IS THIS LEGAL FOR HIGHWAY USE?
This is a cat-back system and retains the catalytic converter. Always check your local regulations.
