Stainless Works Mopar 3.5L V6 Flat Oval Port Header 304SS Exhaust Flanges 1-5/8in Primaries

If you're fabricating custom exhaust headers for a Mopar 3.5L V6 engine, these flat oval port header flanges from Stainless Works are a solid starting point. They are specifically designed to accommodate 1-5/8 inch primary tubes, which is a common size for this engine. Having the right flanges makes a big difference in getting a clean, leak-free seal for your custom exhaust setup.

These flanges are laser-cut from a heavy-duty 3/8 inch thick piece of 304 stainless steel. That thickness is important because it helps prevent the flange from warping when it gets hot from exhaust gases, ensuring a consistent seal over time. The 304 stainless steel itself is well-known for its resistance to corrosion, which is crucial for exhaust components that are exposed to the elements and high temperatures. They come as a pair, so you have what you need for both sides of the V6.
