Diamond Eye Manufacturing 221004 4-Inch Aluminized Steel First Section Tailpipe

The Diamond Eye Manufacturing 221004 is a 4-inch aluminized steel first-section tailpipe engineered for turbo-back and cat-back single-exit exhaust systems on 1994–early 2007 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. It fits all cab and bed length configurations and is the corresponding aluminized counterpart to stainless steel part 261004.

Precision-formed using CNC mandrel bending technology, this tailpipe maintains a consistent 4-inch inner diameter throughout its entire length, minimizing backpressure restrictions and supporting improved exhaust flow for better engine efficiency and lower exhaust gas temperatures (EGTs).

Key Features:

• Material: Aluminized steel construction for corrosion resistance and long service life
• Main Piping Diameter: 4 inches
• Section: First section (1st) of a two-piece tailpipe system
• Mandrel-bent tubing for smooth, unrestricted exhaust flow
• Direct-fit geometry designed to utilize OEM mounting hangers
• Mates to second-section tailpipe 221005 to complete the single side-exit system
• Compatible with all cab and bed lengths for 1994–early 2007 Dodge Ram 2500/3500 5.9L Cummins
• Stainless steel equivalent: 261004

This tailpipe section is a component of Diamond Eye's 4-inch single side-exit exhaust systems. Pair it with the 221005 second section to complete the tailpipe run. Standard 4-inch U-bolt or lap-joint clamps (such as Diamond Eye 444000) are used at the joint between sections.
