Inspired by the concept shown at EICMA in 2024, this exhaust has been designed to seamlessly integrate with the bike's lines. Constructed in one piece from high-grade stainless steel and shaped through the use of high-end technology, with the catalytic converter welded inside the muffler. It is finished with two handmade carbon-fibre covers, which incorporate a double outlet with a honeycomb exhaust protection and an Akrapovič logo in red and white.
If features plug-and-play installation with no remapping required. Focus was placed on optimal throttle response and performance during development, which has resulted in a power increase of 0.3 kW (0.4 hp) at 8,000 rpm and a torque boost of 0.7 Nm at 8,000 rpm when compared to a Yamaha Tracer 9 with a standard stock exhaust system and tested on the Akrapovič in-house dyno. Weight is reduced by 13.2% (1.0 kg) compared to the standard stock exhaust system. Delivering a deep and sporty sound, this full system is EC/ECE type approved and Euro 5+ compliant.
It has been designed so that it can also be mounted in combination with side cases and original Yamaha centre stand.
