Diamond Eye Manufacturing 261004 4-Inch Performance Series Exhaust Pipe First Section Passenger Side

The Diamond Eye Manufacturing 261004 is a 4-inch, first-section, passenger-side exhaust tail pipe engineered for the 1994–Early 2007 Dodge RAM 2500/3500 equipped with the 5.9L Cummins diesel engine. Part of Diamond Eye's Performance Series, this pipe is precision-fabricated in the USA using CNC mandrel bending technology to ensure smooth, unrestricted bends that maximize exhaust flow and minimize backpressure.

Key Features:

• 4-Inch Diameter: Optimized pipe diameter for improved exhaust flow on stock to moderately built 5.9L Cummins applications
• CNC Mandrel Bent: Precision bends maintain full tube diameter throughout for maximum flow efficiency
• Performance Series: Designed as a direct-fit replacement or upgrade component for the passenger-side first exhaust section
• USA Made: Manufactured in-house at Diamond Eye's facility in Athena, Oregon using quality aluminized or stainless steel construction
• Direct Fit: Engineered specifically for all cab and bed length configurations of 1994–Early 2007 Dodge RAM 2500/3500 5.9L Cummins
• OEM Hanger Compatibility: Utilizes factory exhaust hanger locations for straightforward installation

Upgrading to a free-flowing 4-inch exhaust section helps lower exhaust gas temperatures (EGTs), improve throttle response, and extract more power and fuel economy from your Cummins diesel. Diamond Eye components are built to exacting standards and are backed by a manufacturer's limited warranty.
