This neo-retro exhaust shape utilizes a heritage design first used by
Akrapovič 30 years ago, now updated for today’s market with the use of
modern technology, state-of-the-art solutions, and innovative materials. The
complete system is EC/ECE-type approved, with a catalytic converter
incorporated into the layout to make it a Euro 5 product. The muffler
outer sleeve is constructed from high-grade titanium, with stainless
steel for every other component, and the pre-muffler and muffler are
sandblasted for a perfect finish. A black-coated muffler bracket and two
heat shields, designed to protect the riding gear, are included in the
package. The muffler exits on right side of the bike (standard is
underneath), emphasizing the racing and retro look of the machine. The
system delivers a deep, full, and vivid sound allied to a perfect
throttle response, and it adds 1.4 kW (1.9 hp) of power at 9,100 rpm and
increases torque by 1.4 Nm at 9,800 rpm when measured on the Akrapovič
dyno against a Yamaha XSR900 with a standard stock exhaust system. It
has plug-and-play installation, with no remapping needed. This system is
not compatible with the Yamaha original saddlebags.
