Stainless Works Chevrolet LS1/LS6 Round Port Header 304SS Exhaust Flanges 2in Primaries

If you're fabricating custom headers for your LS1 or LS6 Chevrolet engine, these round port header flanges from Stainless Works are a solid starting point. They are specifically designed to work with 2-inch primary tubes, giving you a clean template for building your own exhaust system.

These flanges are laser-cut from a substantial 3/8-inch thick sheet of 304 stainless steel. This heavy-duty construction is key because it helps prevent the flange from warping when exposed to the high temperatures generated by your engine. The round port shape is specific to the LS1 and LS6 cylinder heads, ensuring a good match for those applications. You get a pair of these flanges, ready for your custom fabrication project.
