Diamond Eye K4234A-RP 4 Inch Aluminized Cat-Back Exhaust System Muffler Delete 2004.5-2007.5 Dodge Cummins

The Diamond Eye K4234A-RP is a complete 4-inch cat-back exhaust system designed 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 and features a muffler replacement pipe (straight pipe design) for maximum exhaust flow and an aggressive, unrestricted exhaust tone.

Key Features:

• 4-inch diameter mandrel-bent aluminized steel tubing for improved exhaust flow and durability
• Cat-back single exit design replaces restrictive factory exhaust from the catalytic converter back
• Muffler delete configuration with straight pipe for maximum performance and aggressive sound
• CNC mandrel-bent construction ensures smooth bends and unrestricted flow
• Increases horsepower and torque while improving throttle response
• Helps lower exhaust gas temperatures (EGTs) and can improve fuel economy
• Utilizes factory mounting points and hangers for straightforward installation
• Includes all necessary clamps and hardware for complete installation
• Does not include exhaust tip (allows for custom tip selection)

Built from 16-gauge aluminized steel, this exhaust system provides excellent corrosion resistance and long-lasting durability. The mandrel-bent tubing maintains consistent diameter throughout all bends, eliminating restrictions found in crush-bent factory exhaust systems. This Diamond Eye system is ideal for diesel enthusiasts seeking maximum performance gains and a loud, aggressive exhaust note. Note: This is a straight-pipe configuration and produces significantly more volume than stock, especially under acceleration.
