What is a collector filler diamond used for?

A collector filler diamond is used in 4:1 header designs to fill the gaps between the primary tubes and the collector flange. This helps to square up the tubes and create a solid seal, preventing exhaust leaks.

Why is 304 stainless steel used for this part?

304 stainless steel is chosen for its excellent corrosion resistance. This is important for exhaust components that are exposed to high temperatures and varying weather conditions.

Does this part come with any hardware?

This product listing is for the filler diamond only. Hardware such as bolts or welding supplies are not included and would need to be sourced separately.
