Product Details

Hedman Hedders exhaust header gaskets, also sold as header flange gaskets or exhaust manifold gaskets, are replacement sealing gaskets for Hedman headers. They are made from a gasket material developed specifically for Hedman. The material is built to handle the heat of a header exhaust system.

Key Features:

  • Made from a special gasket material developed by Hedman for header use
  • Malleable material works with the sealing rings around the ports on the head flange to help create a secure seal
  • Made as exact matches to Hedman headers, so the fit and seal are correct
  • Available for a wide range of header applications
  • Made in the USA

Each part number is matched to a specific header or port style. Check your header installation instructions to choose the right gasket number for your headers. Fresh gaskets help keep exhaust leaks away from the flange when you install new headers or service existing ones.

Great experience

Found the correct part for my 1993 motorcycle on Autoplicity at a fair price; half the price that I had previously spent on purchasing a similar K&S part.

Easy process

Kickass

So far so good.
