What is the purpose of a collector filler diamond?

A collector filler diamond is used in 4-into-1 header designs to help square up the ends of the primary tubes where they meet the collector. This ensures a better seal and helps prevent exhaust leaks.

What material is this collector diamond made from?

This filler diamond is made from 304 stainless steel. This material is chosen for its good resistance to corrosion and heat, which is important for exhaust components.

How is the accuracy of this part ensured?

The filler diamond is CNC laser cut. This manufacturing process ensures a high degree of accuracy for a precise fit when installing it into your header collector.

Product Details

When you're building or repairing a set of 4-into-1 headers, getting the collector to seal up tight is key to performance. This collector filler diamond from Stainless Works is designed to help you achieve that. It's made from 304 stainless steel, which is a solid choice for exhaust components because it holds up well against heat and corrosion.

These filler diamonds are CNC laser cut, meaning they're made with a good amount of accuracy. You'll use this piece to square up the ends of your header primary tubes before they enter the collector. Doing this helps ensure a good seal, preventing exhaust leaks right where the tubes come together. It's a small part, but it makes a big difference in getting your headers to perform as they should.
