Stainless Works Chevrolet LS1/LS6 Round Port Header 304SS Exhaust Flanges 1-5/8in Primaries

Laser-cut from heavy-duty 3/8" thick 304 stainless steel, these Stainless Works header flanges are built to handle the high heat of LS1 and LS6 Chevrolet engines. They are specifically designed for 1-5/8" primaries, ensuring a solid foundation for custom exhaust fabrication.

The 3/8" thickness is notable because it greatly resists warping, even under intense exhaust temperatures. This means your custom headers will maintain their seal and integrity over time. Being made from 304 stainless steel also means they're well-built to resist corrosion, keeping them looking good and functioning properly for the long haul.

These flanges come as a pair and are ready for your fabrication project. They are a well-known choice for LS swaps and custom exhaust builds where durability and a precise fit are important.
