Stainless Works 2014+ Chevrolet LT1/LT4 Port Matched Header 304SS Exhaust Flanges 1-7/8in Primaries

If you're building a custom exhaust for your 2014 through 2020 Chevrolet with an LT1 or LT4 engine, these port-matched header flanges from Stainless Works are a solid option. They're designed specifically to work with 1-7/8 inch primary tubes, ensuring a clean seal when you fabricate your own headers.

These flanges are laser-cut from heavy-duty, 3/8 inch thick 304 stainless steel. This thick material is key because it resists warping even when subjected to the high heat that exhaust systems can generate. Using 304 stainless steel also means they'll hold up well against corrosion over time. They come as a pair, ready for your custom header project.
