- BMW R100 R90 R80 R75 R60 R50/5/6/7
- Twinshock manifold 38mm outer diameter with interference tube
- high-quality stainless steel tubes
Note: Some of the old Twinshock RS models had 40mm outer diameter manifolds installed. Here it needs to the exhaust still a small adaptation. You also need two short pipe pieces with an outer diameter of 40mm and an inner diameter of 38mm:

It is easy to make. You need to cut two pieces, in the same length simultaneously to the exhaust channel in your cylinder heads. You just put them first into the exhaust channel and then mount the manifold.
