Product Details

The Diamond Eye Manufacturing 121025 is a 4-inch aluminized steel over-axle tailpipe section designed for single exhaust systems on 1994-2007 Ford F250 and F350 trucks equipped with 7.3L and 6.0L Powerstroke diesel engines. This first section tailpipe is a direct-fit replacement or upgrade component that routes exhaust over the rear axle.

Key Features:

  • Mandrel-bent 4-inch aluminized steel construction for maximum exhaust flow
  • Direct bolt-on fitment for all cab and bed length configurations
  • Over-axle routing design for single exhaust systems
  • Helps reduce exhaust gas temperatures (EGTs) and backpressure
  • Durable aluminized steel finish resists corrosion
  • Compatible with both turbo-back and cat-back exhaust systems

This tailpipe section is manufactured using precision CNC mandrel bending to maintain consistent inner diameter throughout all bends, ensuring smooth exhaust flow and maximum performance. When upgrading to a 4-inch exhaust system, this component provides the quality and fitment that Diamond Eye is known for in the diesel performance market.

Note: For dual exhaust configurations, see part number 122025. This product is not legal for sale or use in California on pollution-controlled vehicles.
