2008-2009 Yamaha R6 Evolution / Racing Hexagonal Full Exhaust Systems by Akrapovic
Akrapovic Racing
and Evolution systems are designed for racing oriented riders who demand maximum
performance from their motorcycle. Both systems are significantly lighter when
compared to the stock exhaust system and feature exceptional production quality,
high-tech materials and of course increased engine performance. The Akrapovic
Racing and Evolution systems were developed to complement the racing character
of the 2008-2009 Yamaha R6.
The Akrapovic RACING and EVOLUTION exhaust systems are composed of
conical header tubes, conical collectors and a conical link pipe. They differ only
in their selection of tubing materials. The RACING uses stainless steel tubes, and the
EVOLUTION titanium. The tubes are attached to each other with sleeve joints secured
with silicon shielded springs. The muffler for both systems is the HEXAGONAL
design, with a titanium inlet cap, perforated inner sleeve and outer sleeve and a
carbon fiber outlet cap. Muffler outer sleeve is available in titanium or
carbon fiber. It is attached to the bike using an Akrapovic carbon fiber clamp. The systems are also
equipped with interference crossover tubes between the two collectors. They also come
with attachments for mounting a lambda sensor.
