Diamond Eye K4110S 4" Aluminized Steel Turbo-Back Exhaust System 2001-2005 Duramax 6.6L

The Diamond Eye K4110S is a complete 4-inch turbo-back exhaust system engineered specifically for 2001-2005 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This system fits all cab and bed length configurations, providing a universal solution for these popular heavy-duty trucks.

Key Features:

• 4-inch mandrel-bent 409 stainless steel construction for maximum exhaust flow and durability
• Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
• Precision mandrel bending maintains consistent tube diameter throughout bends for optimal flow
• 409 stainless steel resists corrosion better than aluminized steel while remaining cost-effective
• Engineered for significant horsepower and torque gains over stock exhaust
• Improves exhaust gas temperature management and turbo spool characteristics
• Direct bolt-on installation with all necessary hardware included
• Fits all cab configurations (Regular, Extended, Crew) and bed lengths

This exhaust system delivers the performance diesel truck owners demand while maintaining the quality standards Diamond Eye Manufacturing is known for. The larger 4-inch diameter significantly reduces exhaust backpressure compared to the factory 3-inch system, allowing your Duramax to breathe freely and produce more power. The mandrel-bent construction ensures smooth, unrestricted flow through every curve of the system.
