Diamond Eye K4308A-RP 4-Inch Aluminized Turbo-Back Dual Exit Exhaust System

The Diamond Eye K4308A-RP is a complete 4-inch aluminized steel turbo-back exhaust system designed specifically for 1994-1997.5 Ford F250/F350 trucks equipped with the 7.3L Powerstroke diesel engine. This high-performance exhaust system features a dual exit configuration and straight pipe design that delivers maximum exhaust flow and an aggressive, commanding exhaust note.

Key Features:

• 4-inch mandrel-bent aluminized steel construction for durability and optimal exhaust flow
• Turbo-back design with 3-inch downpipe for complete exhaust replacement
• Muffler replacement pipe (RP) configuration eliminates muffler for maximum performance and aggressive sound
• Dual exit rear design provides a bold, modern appearance
• Re-incorporates factory catalytic converter for emissions compliance
• Complete kit includes all necessary hangers, clamps, and hardware for installation
• Fits all cab and bed length configurations

Performance Benefits:

• Reduces exhaust backpressure for improved engine breathing
• Lowers exhaust gas temperatures (EGTs) to protect engine components during heavy use
• Provides measurable gains in horsepower and torque
• Improves fuel economy and throttle response
• Enhances the natural turbo whistle and diesel engine tone

The straight pipe configuration delivers an unfiltered, aggressive exhaust note that diesel enthusiasts demand. Diamond Eye's precision CNC mandrel bending ensures smooth, unrestricted bends throughout the system, eliminating flow restrictions found in factory exhausts. The 16-gauge aluminized steel construction provides excellent durability and corrosion resistance at an economical price point. This system allows for future modification flexibility - a muffler can be added later by simply replacing the eliminator pipe section if a quieter tone is desired.

Note: This kit does not include exhaust tips. Tips are sold separately and can be selected based on personal preference.
