2003-2004 5.9L Cummins CAT Delete 5" Turbo-Back Exhaust System

Vigor Diesel's 5-inch turbo-back exhaust, specifically designed for the 2003-2004 Dodge Ram 2500/3500 pickup trucks, unlocks the full potential of your 5.9L Cummins engine. This high-performance upgrade kit is a complete exhaust system that replaces the factory-limited exhaust system after the turbocharger and removes the catalytic converter. Its mufflerless design is intended to provide racing-grade power, durability, and a deep exhaust note.

Product Benefits

Significantly Reduced Exhaust Back Pressure

The 5-inch straight-through design starting from the turbocharger virtually eliminates exhaust back pressure, allowing the Cummins engine to breathe with unprecedented freedom.

Maximize Horsepower and Torque

By removing the catalytic converter and other limiting devices, this system significantly increases horsepower and torque, delivering more robust power output and enhanced traction and performance.

Significantly Reduce Exhaust Temperature

The highly efficient exhaust flow rapidly expels hot exhaust gases, significantly reducing exhaust temperature, crucial for the reliability and performance of the 5.9-liter engine.

Eliminate Long-Term Maintenance

Removing the catalytic converter and related components permanently eliminates the need for maintenance and improves overall engine efficiency.

Exhilarating Turbocharged Diesel Sound

The 5-inch straight-through exhaust pipe, with its muffler-less design, produces a deep, exhilarating sound, unleashing the signature Cummins turbocharger whine.

Compatibility Information

  • ✅ Precisely Compatible: For 2003-2004 Dodge Ram 2500/3500 pickup trucks equipped with the 5.9-liter Cummins turbocharged diesel engine.
  • ❌ Not Compatible with: Standard cab models. Not applicable to cab-and-car chassis models.

Installation and Tuning

Installation

This is a direct-mount turbocharged exhaust system. Due to the complexity of replacing the entire exhaust system, installation by a professional is strongly recommended.

Tuning Requirements

After removing the catalytic converter (CAT) and all related sensors, the ECU needs to be programmed using a tuner that supports DPF removal to clear the engine malfunction indicator lamp and optimize fuel supply to accommodate the new exhaust flow.
