Diamond Eye Manufacturing 261077 5" Aluminized Cat-Back Performance Exhaust Kit 2004.5-Early 2007 Dodge 5.9L Cummins 2500/3500

The Diamond Eye Manufacturing 261077 is a 5-inch aluminized steel cat-back performance exhaust kit designed specifically for 2004.5 through early 2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins turbo diesel engine. This kit is compatible with all cab and bed length configurations, making it a universal fit for the 3rd generation common rail Cummins platform.

Mounting to the catalytic converter outlet, this cat-back system replaces the restrictive factory 4-inch exhaust with a free-flowing 5-inch diameter pipe, helping your Cummins diesel breathe more efficiently. The result is improved exhaust scavenging that can contribute to increased power output, enhanced throttle response, and better fuel economy.

Key Features:

• 5-inch aluminized steel construction — durable, corrosion-resistant material widely used in performance exhaust applications
• Cat-back design — connects at the catalytic converter for a straightforward installation without turbo or downpipe modifications
• CNC mandrel-bent tubing — maintains consistent inner diameter throughout every bend for maximum exhaust flow
• Single side exit configuration — clean, factory-style routing with a performance upgrade
• Fits all cab and bed lengths — compatible with Regular, Quad, and Mega Cab; Short, Long, and Dually bed configurations
• Deep, aggressive exhaust tone — delivers a bold diesel sound without excessive cabin drone

Diamond Eye Manufacturing produces its exhaust components using precision CNC mandrel bending equipment, offering tube processing from 3/8" to 5" OD in both aluminized and stainless steel. The 261077 kit is engineered to maximize performance gains from your 5.9L Cummins without compromising daily drivability.
