Product Details

The Diamond Eye 321051 is a complete 4-inch turbo-back exhaust system designed specifically for 2001-2007.5 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This performance exhaust system fits all cab configurations and bed lengths, providing a universal solution for these popular heavy-duty trucks.

Key Features:

  • 4-inch mandrel-bent aluminized steel tubing for maximum exhaust flow and durability
  • Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
  • Precision CNC mandrel bends maintain consistent pipe diameter throughout
  • Compatible with all cab and bed length configurations
  • Engineered to improve horsepower, torque, and fuel efficiency
  • Reduces exhaust gas temperatures (EGTs) for better engine longevity
  • All necessary hardware and installation instructions included

Diamond Eye's mandrel-bent construction eliminates the crimped bends found in crush-bent exhaust systems, ensuring unrestricted exhaust flow. This system is designed to provide maximum performance gains while maintaining excellent fit and finish. The aluminized steel construction offers superior corrosion resistance for long-lasting durability in all weather conditions.
