Product Details

The Diamond Eye 321046 is a 4-inch aluminized steel intermediate exhaust pipe engineered for the 6.6L Duramax diesel engine. Precision CNC mandrel-bent to maintain a consistent inner diameter throughout every curve, this pipe maximizes exhaust flow for improved diesel performance and reduced exhaust gas temperatures (EGTs).

Key Features:

  • 4-inch outer diameter aluminized steel construction for durability and corrosion resistance
  • CNC mandrel-bent tubing ensures unrestricted exhaust flow with no kinks or crimps
  • Direct-fit replacement — designed specifically for all cab and bed length configurations
  • Sold individually
  • Made in the USA at Diamond Eye's manufacturing facility in eastern Oregon
  • Designed for performance/racing applications — note: eliminates converters, which may affect emissions compliance in your area

Diamond Eye Performance is a leading manufacturer of diesel exhaust components, producing everything in-house using advanced CNC mandrel bending equipment. Note: This pipe eliminates catalytic converters and is intended for off-road or racing use. Check local emissions regulations before installing.
