A special exhaust manifold gasket is included, that is port matched to the header primary flange. This gaskets openings are a little larger than a factory OEM Honda gasket.

This header has been out on the market now for some time, but until all of our testing was complete, could we offer it to our customers. This header makes good power and is excellent for use on mildly modded to highly modified B-series powerplants. For the great economic value, this header is a great buy.
