Diamond Eye Manufacturing 362005 4-Inch Stainless Exhaust Pipe First Section Passenger Side Duramax 6.6L

The Diamond Eye Manufacturing 362005 is a 4-inch diameter, stainless steel exhaust pipe designed as the first section, passenger-side replacement for the Performance Series exhaust on 2001–Early 2007 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. It is compatible with all cab and bed length configurations.

Manufactured using CNC mandrel bending technology, this pipe features smooth, unrestricted bends that maintain consistent inner diameter throughout, maximizing exhaust flow compared to traditional crush-bent alternatives. The result is reduced exhaust backpressure, which helps unlock additional horsepower and torque, improve throttle response, lower exhaust gas temperatures (EGTs), and increase fuel economy.

Key Features:

• 4-inch diameter stainless steel construction for long-lasting corrosion resistance
• CNC mandrel-bent tubing for smooth bends and maximum exhaust flow
• First section, passenger-side fitment for 2001–Early 2007 Chevy/GMC 6.6L Duramax diesel
• Compatible with all cab and bed lengths — no trimming or modification required
• Part of Diamond Eye's Performance Series diesel exhaust lineup
• Designed to utilize OEM hanger locations for a direct-fit installation
• Manufactured in-house in Athena, Oregon using precision exhaust fabrication equipment

Whether replacing a worn section or building out a full Performance Series exhaust system, the Diamond Eye 362005 delivers a direct-fit, high-flow solution engineered specifically for the 6.6L Duramax diesel platform.
