For the Honda CBR 125 we offer you here the racing exhaust system Arrow Thunder in black. Compared to the standard exhaust, the sound seems much louder. Since the manifold is perfectly tuned to the engine, you can even increase your performance a bit. You can also find the matching manifold in our shop under the number 51002MI. We deliver the muffler with EG-type approval. But if you don't have a catalytic converter you can get problems at the TÜV and AU.
