We have finished our first production run of our billet center section T4 and T6 exhaust manifolds. Available in 12v and 24v port design. These are a straight flange designed for increased flow and faster spool up. We have been testing these for several years now on a variety of trucks (and pulling tractors) with great results. They come Ceramic coated and include the studs and nuts to mount the manifold to the head.
