By Kern Premium Exhaust, painted black for Harley-Davidson Softail models with classic exhaust layout. (Delux)

The By Kern Premium Exhaust is your best choice if you want a good-sound bike so that your neighbors love it. We’ve created an exhaust for you that meets the European Union requirements, not reaching the 80 dBa sound level on official measurements, but you can still get the real Harley feeling with one switch. The By Kern Premium exhaust has two types of sound, street and sport. The Silent Mode (Street) is classified as “e7” in accordance with EC Directive 97/24, approved by the European Union. Installed with Euro 4 catalytic converter. Pass-by noise level is below 80 dbA.

You have chosen a Harley-Davidson Softail exhaust with classic layout (Delux) in painted black finish.


You can fit the By Kern exhaust, replacing your factory exhaust. (slip-on) There is no need to make any changes to the factory settings, if you feel good enough and take responsibility, you can install it by yourself. The mechanism allows you to choose the volume you want to ride with. There is only one moving part inside the exhaust to minimize the possibility of error or dysfunction. It is connected to stainless steel cables with a self-developed mechanical tone switch. This switch is mounted on the left-hand frame tube under the petrol tank. This is in default position for Street sound. Turn the lever to change to the Sport sound and press the button to return to Street sound.
