Our manifolds are exclusively manufacured from 1.4828 heat resistant stainless steel pipes.In contrast to conventional stainless steel the 1.4828 stands out with a minor thermal expansion, a high tensile strength and scaling resistance when temperatures are high.These are shock-charging manifolds which merge from 4 pipes into one with a laser cut collector.The outside diameters are 42,3x2mm and 48,4x2mm.The manifolds are welded with Wig. procedures and naturally formed.This manifold has a K04 Flange. We also offer others on request. Additional exhaust temperatur or pressure ports also on request.The flange plate to cylinder head is face milled after welding.K04 Turbocharger is in original position.With these manifolds and appropriate surrounding a performance of over 1000 hp is possible.Also in scope of supply are secondary closure plates.We have chosen the pipe layout in a way that we can always use a entire pipe bend which means no cross section constriction. Because of this we also removed (useless) secondary air valves.
