Diamond Eye 220098 4-Inch Performance Exhaust Pipe 1989-1993 Dodge Ram Cummins

The Diamond Eye 220098 is a 4-inch performance exhaust pipe designed specifically for 1989-1993 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine and 2WD configuration. This first section exhaust pipe is engineered to replace the restrictive factory exhaust system with a free-flowing performance design.

Key Features:

• Mandrel-bent construction maintains consistent 4-inch diameter throughout for maximum exhaust flow
• CNC precision-bent tubing ensures proper fitment and performance
• Heavy-duty 16-gauge steel construction for long-lasting durability
• Direct bolt-on replacement for the factory first section exhaust pipe
• Compatible with all cab and bed length configurations on 2WD models
• Reduces backpressure and exhaust gas temperatures for improved engine performance

This exhaust pipe is part of Diamond Eye's Performance Series and is manufactured using advanced CNC mandrel bending technology to maintain smooth internal diameter throughout all bends, eliminating turbulence and restrictions found in crush-bent factory exhaust systems. The mandrel-bent design allows for better exhaust flow, which can result in improved horsepower, torque, and fuel efficiency while reducing exhaust gas temperatures in your first-generation Dodge Cummins diesel.
