All of our Exhaust Manifolds are stainless steel, back purged, and TIG welded by hand in North America. Careful consideration for runner length, collector design, orientation, wastegate placement, and turbine flow characteristics ensure optimal performance.
Our RB25 and RB26 manifolds allows for adaption to your turbocharger and wastegate of choice, and can be built with a merge collector for single volute turbines, or a divided collector orientation and dual wastegates for twin scroll turbines. Turbular exhaust manifold for bottom or top mount twin turbochargers are also available. Please contact us if you are looking to match a turbocharger that is not listed.
