Diamond Eye 220099 4" Turbo-Back Exhaust System 1989-1993 Dodge Ram Cummins 5.9L

The Diamond Eye Manufacturing 220099 is a complete 4-inch turbo-back exhaust system engineered specifically for 1989-1993 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine in 2WD 4x2 configurations. This performance exhaust system is designed to work with all cab and bed length combinations.

Key Features:

• 4-inch mandrel-bent tubing for maximum exhaust flow and reduced backpressure
• Turbo-back design for optimal turbocharger performance and efficiency
• Precision-engineered fitment for 1989-1993 Dodge Ram Cummins applications
• Manufactured using CNC mandrel bending equipment for consistent quality
• Compatible with all cab styles (Regular, Club, Crew) and bed lengths
• Designed specifically for 2WD (4x2) configurations only

Diamond Eye's mandrel-bent construction maintains constant pipe diameter throughout bends, ensuring smooth exhaust flow and maximizing power gains. This system helps reduce exhaust gas temperatures, improve throttle response, and increase fuel economy while delivering a deeper, more aggressive exhaust note. The complete turbo-back design replaces restrictive factory exhaust components from the turbocharger outlet to the rear exit.
