Product Details

This 4-inch aluminized turbo back exhaust system from Diamond Eye Performance is built for your 1989-1993 Dodge W250 or W350 equipped with the 5.9L Cummins diesel engine. The kit replaces your factory exhaust from the turbocharger all the way back, offering a significant upgrade in flow and sound for your 4-wheel drive truck.

Diamond Eye uses CNC mandrel bending to shape the aluminized steel tubing. This process ensures consistent tube diameter throughout the bends, which helps maintain exhaust gas velocity and improves flow compared to crush bends. Aluminized steel offers good corrosion resistance for everyday use, making it a solid choice for a performance exhaust system that needs to hold up over time. This kit is designed as a direct replacement, meaning it should bolt up to your existing turbocharger and frame mounts, simplifying the installation process.

This system is specifically for 4-wheel drive models. It's important to note that this exhaust system is not CARB approved and cannot be shipped to California. If you're looking to improve the exhaust flow and sound on your Cummins-powered Dodge truck, this turbo back kit from Diamond Eye is a well-built option.
