Stainless Works Small Block Chevy Round Port Header 304SS Exhaust Flanges 1-5/8in Primaries

Stainless Works has a reputation for making solid exhaust parts, and these header flanges are no exception. If you're building a custom exhaust for your Small Block Chevy, these round port flanges are designed to help you get the job done right. They're made specifically for 1-5/8 inch primary tubes, which is a common size for many performance builds.

What sets these apart is the material and how they're made. They're laser-cut from heavy-duty 3/8 inch thick 304 stainless steel. This thick material is important because it resists warping, even when things get really hot under the hood. The 304 stainless steel also means they'll hold up well against corrosion over time. You get a pair of these flanges, ready for your fabrication project.
