What is a collector filler diamond used for?

A collector filler diamond is used in 4-into-1 headers to help square up the primary tubes where they enter the collector. This ensures a tighter fit and helps prevent exhaust leaks.

Why is 304 stainless steel used for this part?

304 stainless steel is chosen for exhaust components because it offers good resistance to corrosion and heat. This helps the part last longer in the harsh exhaust environment.

Product Details

When you're building or repairing a set of 4-into-1 headers, getting a solid seal at the collector is key to performance. This 1-1/2 inch diameter filler diamond from Stainless Works is designed to help you achieve that. It's made from 304 stainless steel, which is a good choice for exhaust components because it holds up well against corrosion.

These filler diamonds are CNC laser cut, meaning they're precisely shaped for a good fit. They work by squaring up the header primary tubes where they meet the collector, which helps prevent exhaust leaks. A leak-free collector means your exhaust gases flow where they're supposed to, contributing to better performance.
