Diamond Eye Manufacturing 261079 4" Aluminized Performance Exhaust Pipe Section 2004.5-Early 2007 Dodge 5.9L Cummins 2500/3500

The Diamond Eye Manufacturing 261079 is a Performance Series exhaust pipe section designed specifically for 2004.5 through Early 2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins diesel engine. This direct-fit replacement and upgrade pipe is compatible with all cab and bed length configurations, making it a versatile solution for a wide range of third-generation Cummins-powered trucks.

Manufactured in-house at Diamond Eye's facility in Athena, Oregon, this exhaust pipe section features CNC mandrel-bent tubing for smooth, unrestricted bends that maximize exhaust flow. Unlike crush-bent pipes, mandrel bending preserves the full inner diameter throughout every curve, helping to eliminate backpressure that robs your diesel engine of power and efficiency.

Key Features:

• CNC mandrel-bent tubing for maximum exhaust flow and minimal backpressure
• Constructed from 16-gauge aluminized steel for durability and corrosion resistance
• Direct-fit design — utilizes OEM hanger locations for straightforward installation
• Fits all cab and bed length combinations on 2004.5–Early 2007 Dodge Ram 2500/3500
• Designed for use with 5.9L Cummins diesel engines
• Part of Diamond Eye's Performance Series exhaust lineup
• Made in the USA

Upgrading your exhaust system with properly flowing pipe sections like the 261079 can contribute to lower exhaust gas temperatures (EGTs), improved throttle response, and enhanced horsepower and torque by freeing up restriction in the exhaust path. This pipe section is designed to integrate seamlessly with Diamond Eye's full Performance Series exhaust systems or as a standalone replacement piece.
