DIAMOND EYE K4234A CAT BACK EXHAUST SYSTEM FOR 04.5–07.5 DODGE RAM 2500/3500 4 INCH SINGLE SIDE WITH MUFFLER ALUMINIZED

DIAMOND EYE K4234A is a 4.0" aluminized steel cat-back exhaust for 2004.5–2007.5 Dodge Ram 2500/3500 5.9L Cummins. It replaces the system behind the catalytic converter with mandrel-bent tubing, a straight-through muffler, and a single passenger-side exit for lower backpressure, cooler EGTs, and a confident, deep tone.

FAQ: WILL THIS FIT MY TRUCK?

Yes—if you have a 2004.5, 2005, 2006, or early 2007 Dodge/Ram 2500 or 3500 with the 5.9L Cummins (all cab/bed lengths). This kit is cat-back and designed for trucks equipped with a catalytic converter. It will not fit 2003–early 2004 (non-cat) without additional parts.

FAQ: WHAT MATERIAL AND SOUND?

Aluminized steel for strong corrosion resistance at a lower cost. The straight-through muffler yields a deeper tone than stock without excessive in-cab drone on most trucks.

FAQ: WHAT COMES IN THE BOX?

Cat-back tubing sections, performance muffler, tailpipe, and clamps/hardware as supplied by Diamond Eye. Reuses factory-style hangers.
