Diamond Eye Manufacturing K4234S-RP 4 Inch Turbo-Back Exhaust System 2004.5-2007 Dodge Cummins

The Diamond Eye K4234S-RP is a complete 4-inch turbo-back exhaust system engineered specifically for 2004.5-2007.5 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This system fits all cab and bed length configurations, providing a universal solution for these model years.

Key Features:

• 4-inch mandrel-bent 409 stainless steel tubing for maximum exhaust flow and durability
• Turbo-back design replaces restrictive factory exhaust from turbocharger to tailpipe
• Mandrel bending maintains consistent pipe diameter throughout bends, eliminating flow restrictions
• 409 stainless steel construction resists corrosion and withstands high exhaust temperatures
• Universal fit for all 2004.5-2007.5 Dodge Ram 2500/3500 cab and bed configurations
• Engineered to reduce exhaust gas temperatures and backpressure
• Improves throttle response, fuel economy, and engine performance

Diamond Eye Manufacturing utilizes precision CNC mandrel bending technology to create exhaust systems that maximize flow while maintaining structural integrity. The 4-inch diameter provides significantly improved exhaust flow over the factory 3-inch system, making this an ideal upgrade for both stock and modified Cummins diesel engines. The 409 stainless steel material offers an excellent balance of durability and value, providing superior corrosion resistance compared to aluminized steel.
