Stainless Works BBC Round Port 304SS Exhaust Flanges 2-1/2in Primaries (Raised Port Heads Only)

Stainless Works is known for making well-built exhaust components, and these Big Block Chevy round port header flanges are no exception. If you're working on a Big Block Chevy with raised port heads, these flanges are designed specifically for that setup. They're made to work with 2-1/2 inch primaries, ensuring a solid connection for your custom headers.

These flanges are laser-cut from a heavy-duty 3/8 inch thick piece of 304 stainless steel. That thick material is key because it helps resist warping, even when things get really hot under the hood. The 304 stainless steel itself is also chosen for its ability to stand up to high heat and resist corrosion. You get a pair of these flanges, ready for your fabrication project.
