Adapter sleeves Exhaust BMW R45-R100 40 mm / 38 mm
The BMW Boxer models have two different outlet diameters on the cylinder heads ex works. Our BDM Shorty exhaust system is delivered as standard in the 38 mm version. But so that you can mount the exhaust system on motorcycles with 40 mm manifold outlet, you will now find the suitable adapter sleeves in perfect length.
Installation instructions: The adapter sleeves must be mounted flush on the manifold tubes by hand, or if not possible (manufacturing tolerances), with light rubber hammer blows. The sale takes place in the set.
