PRODUCT OVERVIEW
The Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to
control the sound of the system from the cockpit of their vehicle. Using Akrapovič
technology, the driver can easily switch between two distinctive sound modes.
As an alternative to the Sound Remote Controller, Akrapovič has created a
smartphone app (for iOS and Android) to provide an even better connection to the
receiver.
The operation of the Akrapovič Sound Kit using the Akrapovič Car Sound Kit App
requires the PIN pairing code, which is permanently written on the sound receiver
and is printed on the back cover of this manual. KEEP THIS MANUAL FOR FURTHER
REFERENCE because the PIN pairing code is unique to a particular
Akrapovič Sound Kit and cannot be retrieved if it is lost or if its inscription on the
sound receiver becomes unreadable or inaccessible.
In case of replacement of the Receiver, Sound Remote Controller must also be
replaced, since it is not transferable between Receivers after it has been paired.
It is possible to use the Akrapovič Sound Kit with more than one Sound Remote
Controller (not at the same time). Additional Sound Remote Controllers can be
purchased separately - contact your local authorized Akrapovič partner for more
information.

SAFETY WARNINGS
Road Safety
To avoid traffic accidents, use the Akrapovič Sound Kit system
responsibly and safely, and always obey local traffic rules.
Use of the Sound Remote Controller and the Akrapovič Car Sound Kit App
while driving may cause distraction, so avoid operating the Akrapovič
Sound Kit system in circumstances that prevent you from focusing on
safe driving. Using a smartphone while driving may be prohibited in
some countries - check local traffic rules.
Note that using the Akrapovič Sound Kit system influences the engine
response and torque generated, causing certain changes in the vehicle
response - therefore do not use the Akrapovič Sound Kit system in
poor weather conditions. When using the Akrapovič Sound Kit, always
consider the road and traffic conditions.
Use of the Sound Remote Controller and/or Akrapovič Car Sound Kit
App by persons other than the driver (especially children) and

consequently unexpected changes both sound modes in uncontrolled
circumstances may take drivers by surprise, endangering the safety of the
passengers in the vehicle and/or other road users or causing interference-
related malfunctions. Refer to the Interference section below.
Interference
All wireless devices are susceptible to or may cause interference. Do
not use the Sound Remote Controller in environments where such
interference might cause malfunction of machines or devices and/or
endanger the lives of others (e.g., in airplanes, in hospitals, or near medical
equipment or implanted medical devices) as well as in places where the
use of wireless devices is prohibited or restricted.
Child Safety
The Sound Remote Controller should be kept out of reach of children
because it contains small parts. The Sound Remote Controller and/or
Akrapovič Car Sound Kit App should not be operated by children. Refer to
the Road Safety section above.

For the Sound Remote Controller to work, it must be paired with the sound
receiver. The (original) Akrapovič exhaust system with the valves and sound
receiver must first be installed. Refer to the Akrapovič exhaust system and
the Akrapovič Sound Kit Installation Manual.
To pair the Sound Remote Controller with the sound receiver, press and
hold the button on the Sound Remote Controller until the red LED starts
flashing. Switch the car ON to supply the sound receiver.
The pairing process will occur automatically within ten seconds. If the
pairing process is completed successfully, the LED (white or red) on the
Sound Remote Controller will turn on for fifteen seconds.

happens, you should repeat the complete pairing process.
After the pairing process is completed, the Sound Remote Controller can
only be used with the corresponding installed and paired receiver.
The pairing process must be completed before the first use of the
Akrapovič Sound Kit.

Adaptive Race
OPERATING OF THE VALVES IN
DIFFERENT CAR MODES
Sound mode 1 can also be called Adaptive mode. In this mode, valve
operation depends on the selected car mode (Efficient, Sport and Sport+),
pedal position and engine speed. This mode is optimized for every day use
with its balance of engine performance and sound experience.
Sound mode 2 can also be called Race mode. Valves can be completlly
controled with optional Akrapovic sound kit Remote or mobile app and
can be opened/closed at any time - if closing of the valves does not effect
the engine performance. This mode is intended to be used for racing
purposes only.

No color: sleep mode
Orange:battery level too low to operate
or detected default on the battery
If the button is not pressed for a full fifteen seconds, the Sound Remote
Controller enters sleep mode until the next time it is pressed.
Note that the valves are by default always in Sound mode 1 position
when the engine is started. If the Sound Remote Controller stops
operating during driving (e.g., the battery runs out, or the Sound Remote
Controller is damaged or is not functioning due to some other technical
reason), switching between the modes will be automatically managed by
switching between different car modes (Efficient, Sport and Sport+).
At the next engine start, the default mode is applied.
The Sound Remote Controller will not function when the Akrapovič Car
Sound Kit App is connected.
