Product Descripton:

Dougs Headers, the most respected name in the header industry since the 60s, began in 1958 as a small muffler shop in East Los Angeles, California.

Every Dougs header comes with all the necessary mounting hardware, collector reducers or connector pipes, premium gaskets and detailed installation instruction sheets. Our extra thick gaskets are rated up to 1100F, pressures to 3700 psig (255 bar), and are designed for an exact port match with Dougs headers.
