Premium Exhausts

The By Kern Premium exhaust offers two sound options: Street and Sport.

• The quiet mode (Street) is certified with the “e7” marking according to the European Union’s EK 97/24 directive. It comes equipped with a catalytic converter. The drive-by noise level is below 80 dBA.

Testing was performed precisely and under conditions that meet all required standards.

• For off-road use, a much more powerful sound (Sport) is also available. This sound does not comply with EU regulations, as the control valve is not included in the certification. Therefore, using it on public roads is entirely at your own risk. The drive-by noise level exceeds 105 dBA.

The exhaust is made of stainless steel without any additional surface treatment. The polished finish is naturally glossy and will not turn dull. However, a matte black painted version is also available.

The exhaust fits directly onto the original headers and mounting brackets.

The exhaust tips are included in the price — you can choose the one that matches your taste. Please select your preferred option when placing your order.

IMPORTANT!

Every motorcycle is different, so we recommend having your bike calibrated after replacing the exhaust.

We suggest a professional dyno tuning. Incorrect setup, including improper calibration, can cause excessive heat in the components, which may damage the exhaust.

The warranty does not apply to engines that are not or are incorrectly configured. We do not assume responsibility for such cases.
