Exhaust Restrictor and Manifold for the Mini Max racing engine. This component secures to the exhaust port of the engine with two M8 hex head screws and supports the flow of exhaust gases into the silencer. With new regulations as of January 2020, the MY20 exhaust system has changed to feature an exhaust manifold 22.0 mm in inner diameter.
Each exhaust manifold features a milled step that provides a position to place the exhaust gasket to properly fit the silencer system, and also includes integrated exhaust spring rings to keep the assembly tightly fitted together.
The manifold is sold separately, or as part of the Rotax MY 20 upgrade kit.
