Note on using your new exhaust system
Please read the following information to ensure the best riding experience:
⚠️ If you ride for a long time at very low RPM, especially with DCT models, the engine warning light may come on. This can happen because of higher exhaust back pressure. It can cause different readings from the lambda sensor behind the catalytic converter, also called a Lambda 2 error.
➡️ Do not worry: this is not a defect. With normal or faster riding, this usually does not happen. If the warning light comes on after riding at low RPM, it normally goes off again by itself after about 200 km of normal or faster riding. Please have the error checked by a Honda dealer. The reason is the slightly smaller inner volume of our Breaker II silencer compared to the original silencer.
✅ We have already improved our Breaker II silencer. In our test rides, this prevented the engine warning light from coming on in more than 90% of cases. From 2026, our new Stormbreaker double-pipe silencer will be available for Honda CMX 1100 models. With this silencer, the described issue will no longer occur.
We kindly ask for your understanding. These changes are necessary because of the Euro 5+ standard.
For any questions, we are happy to help.

Perfectly complements the bike
I recently installed the Breaker II tapered matte black exhaust on my Honda CMX 1100 Rebel, and the whole experience has been excellent from start to finish. Installation was straightforward, thanks to the clear instructions, and everything needed for mounting was included in the package.
The exhaust itself is beautifully finished, with a sleek matt black look that perfectly complements the bike. In my opinion, it’s a huge improvement over the somewhat bulky stock exhaust—it really refines the overall appearance.
But the real highlight is the sound. It’s deep, rich, and full of character. When downshifting, it regularly produces those satisfying pops and bangs, which are an absolute pleasure to hear and add a lot to the riding experience.
Another important factor for me—and ultimately what made me choose this brand—is that the exhaust remains road-legal in terms of sound. That’s crucial, especially when planning motorcycle trips abroad where regulations can be strict.
All in all, it’s a fantastic upgrade that enhances both the look and feel of the bike without compromising on legality.
