Diamond Eye K5131A 5-Inch Aluminized Turbo-Back Exhaust System 2007.5-2010 GM Duramax LMM

The Diamond Eye K5131A is a complete 5-inch aluminized steel turbo-back exhaust system engineered specifically for 2007.5-2010 Chevrolet/GMC 2500HD and 3500HD trucks equipped with the 6.6L LMM Duramax diesel engine. This universal-fit system accommodates all cab configurations and bed lengths, providing a direct bolt-on solution for improved exhaust flow and performance.

Key Features:

• 5-inch mandrel-bent aluminized steel construction for maximum durability and corrosion resistance
• Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
• Precision mandrel bending maintains consistent diameter throughout for optimal exhaust flow
• Universal fit compatible with all 2007.5-2010 Duramax LMM cab and bed configurations
• Complete system includes all necessary pipes, clamps, and hardware for installation
• Reduced exhaust gas temperatures and backpressure for improved engine efficiency
• Enhanced throttle response and potential gains in horsepower and torque

Diamond Eye Manufacturing utilizes advanced CNC mandrel bending technology to create smooth, consistent bends that eliminate turbulence and maximize exhaust velocity. The 5-inch diameter provides significant flow improvements over the restrictive factory 3-inch system, making this an ideal upgrade for both stock and modified Duramax engines. The aluminized steel construction offers excellent protection against the elements while maintaining an affordable price point compared to stainless steel alternatives.
