KessTech is the expert when it comes to manually and electronically adjustable exhaust systems for motorcycles. Our adjustable exhaust systems enable the biker an awesome driving experience – the true and original driving fun. Full-Volume Sound because of the valve positioned at the end of the muffler, optimized performance and an absolute eye-catcher! Never heard it? Well, now's the time!

While using our electronic sound systems you can switch between the different sound modes. In every mode including the Full-Volume Sound in the ON mode but also in the MEDIUM and OFF mode all legal requirements are met regarding performance, exhaust gas emission and sound emission. In the OFF mode you are even more quiet than the original exhaust.
