Diamond Eye K4236A-RP 4 Inch Cat-Back Dual Exhaust System Aluminized No Muffler

The Diamond Eye K4236A-RP is a complete 4-inch cat-back dual exhaust system engineered specifically for 2004.5-2007 Dodge RAM 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This performance exhaust system features a straight pipe configuration with no muffler, delivering maximum exhaust flow and an aggressive, unfiltered exhaust note that makes a bold statement on the road.

Key Features:

• 4-inch mandrel-bent aluminized steel construction for durability and corrosion resistance
• Straight pipe eliminator configuration eliminates restrictive factory muffler
• Dual split-side exit design for enhanced appearance and improved exhaust flow
• Reduces backpressure to lower exhaust gas temperatures (EGTs) during towing and heavy loads
• Increases horsepower and torque with improved exhaust scavenging
• May improve fuel economy through enhanced engine efficiency
• Compatible with all cab and bed length configurations
• Complete kit includes all necessary hardware and installation instructions
• Made in the USA at Diamond Eye's facility in Athena, Oregon

This system utilizes precision mandrel-bent tubing that maintains consistent pipe diameter throughout all bends, eliminating the crimps and restrictions found in factory exhaust systems. The aluminized steel construction offers excellent durability and rust resistance at an economical price point. Installation can typically be completed in approximately one hour using common hand tools. Note that exhaust tips are not included with this kit and must be purchased separately. A muffler can be added later by replacing the eliminator pipe if desired to moderate sound levels.
