The ultimate collector for making exhaust manifolds for maximum performance. Machined from a solid billet of 321/1.4541 stainless steel for superior high-temperature durability. Featuring smooth transitions, and exact dimensions for the best flow possible. This translates into less back pressure, and means more power with the same boost, or the same power with lower boost (and less lag)!
This CNC billet turbo collector features chamfered entry pipes to make welding as simple as possible. This ready-to-weld part cuts hours or days off your exhaust manifold build time, and gives you a much better exhaust manifold!
This collector also features large cuts from the ports into the wastegate as well as a large chamfer on the lower inside edge of the wastegate, improving flow both to the turbo and the wastegate.
Designed for 42.4x2mm pipes/tubes, also a reasonably good match for 1.25" sch10 pipe, resulting in a weight of only 614gr!
