Our ZZ Diesel T-4 Mount Stainless Steel Exhaust Manifolds come with 2 ports drilled and tapped for probes. This is a high quality cast stainless steel manifold that is cnc machined. The edges are chamfered/debured. The manifolds have 3/4 inch thick center section. This makes it nice for sled pullers and drag racers to custom port it. The thick wall casting will help keep heat in. The inside runner sizing is 1.650 inches all the way to the center outlet for high flow.
