Stainless Works Chevrolet LS1/LS6 Round Port Header 304SS Exhaust Flanges 1-7/8in Primaries

What you get here are a pair of Stainless Works header exhaust flanges, specifically made for LS1 and LS6 Chevrolet engines with round ports. These are designed to work with 1-7/8 inch primary tubes, which is a common size for performance exhaust builds on these engines. They are laser-cut from a solid piece of 3/8 inch thick 304 stainless steel, giving you a strong foundation for your custom headers.

The reason for using 3/8 inch thick stainless steel is to prevent warping, even when things get really hot. High exhaust temperatures can easily warp thinner metal, leading to leaks. This heavy-duty construction ensures a solid seal and longevity for your custom header project. The 304 stainless steel also offers good resistance to corrosion.
