What is the purpose of a collector filler diamond?

A collector filler diamond is used to precisely square up header primary tubes within the collector. This ensures a tight seal and helps eliminate exhaust leaks at the collector junction.

What material is this collector diamond made from?

This collector diamond is constructed from 304 stainless steel, which offers excellent resistance to corrosion and is well-suited for exhaust system components.

Is this part compatible with all exhaust headers?

This filler diamond is specifically designed for 4:1 header configurations. It is a universal part, but you should confirm it will properly mate with your specific header primaries and collector.
