Product Details

The Diamond Eye Manufacturing 524521 is a precision-engineered 4-inch performance exhaust elbow constructed from 409 stainless steel. This mandrel-bent elbow is designed for diesel exhaust systems where smooth, unrestricted flow is critical for maintaining optimal exhaust velocity and reducing backpressure.

Key Features:

  • 4-inch diameter for high-flow diesel exhaust applications
  • 409 stainless steel construction for durability and corrosion resistance
  • Mandrel-bent design maintains consistent inner diameter throughout the bend
  • Precision CNC manufacturing ensures proper fitment and alignment
  • Ideal for custom exhaust fabrication and turbo diesel performance builds

Mandrel bending technology ensures the tubing maintains its full 4-inch inner diameter through the curve, eliminating the crimping and flow restrictions common with crush-bent elbows. The 409 stainless steel material offers excellent heat resistance and longevity in demanding exhaust environments, making this elbow a reliable component for diesel performance upgrades and custom exhaust systems.

Great experience with the process of order.

WE COULD HAVE BOUGHT IT FROM THE SUPPLIER OURSELVES. WE CHOSE YOU, IT WOULD HAVE BEEN NICE IF YOU HAD IT ON HAND LIKE YOU INDICATED ... WE ENDED UP HAVING OUR CUSTOMER WAIT FOR AN ADDITIONAL WEEK.

Not only did you have my hard-to-find or out-of-stock item, you had thirty-five of them. I only needed one and your price was great and the delivery time was good. I did contact your customer service department and spoke with Jennifer V. She added to a very pleasant shopping experience. Thank you.
