Absolute premium exhaust system from Giannelli for the Yamaha MT 125 model type RE11 before 2017.
The end cap of the exhaust system is completely made of real carbon. The casing of the exhaust system is finished with titanium sheet metal. A suitable manifold and the necessary mounting material is included with the exhaust system. In general the exhaust system has a printed E-number, but is delivered without catalytic converter.
If you want to be on the safe side with the exhaust system as well as with the AU, you should also order the catalytic converter 70512CT.
