BMW R 1200 GS connection tube from 2010 without catalytic converter、 without CE Approval/Genera The BMW R1200GS has a pre-silencer separate from the rear silencer as standard. Because of this you can either just replace the pre-silencer (because of the catalytic converter) or just the rear silencer (because of the sound or the appearance). All parts are compatible with each other. - instead of the pre-silencer、 without General Certification - with manifold - replaces the catalytic converter - the lambda probe is still being used. - the manifold exhaust flap is still being used.
Particularly for trips in countries where there is no unleaded petrol.
