About this part

Product Details

Stainless Works is known for making well-built exhaust components right here in the USA. This 1-7/8 inch diameter collector filler diamond is a prime example of their attention to detail. It’s designed to help you get a solid seal when you’re building or repairing 4-into-1 headers.

Crafted from 304 stainless steel, this piece offers good resistance to corrosion, which is important for exhaust parts. The CNC laser cutting ensures accuracy, meaning it fits precisely where it needs to. Its main job is to square up the header primary tubes before they enter the collector, preventing leaks and ensuring a clean exhaust flow. This is a small but critical part for anyone fabricating or modifying headers.
