We believe that we have produced the ultimate exhaust system for the 889cc CP3 engined Yamaha XSR and MT09 (Model year 2021 onwards). Anyone that has ridden these bikes knows how fantastic they are, but they leave the factory muted and restricted by Euro 5 emissions regulations. To unleash the true potential of these bikes they desperately need liberating from the imposed restrictions.
A huge amount of time was spent on the development of this exhaust system. We spend many hours in the dyno cell data logging and perfecting our ECU remapping strategy before embarking on designing the exhaust. Our map writers and hardware designers worked hand in hand to achieve this goal. We used all our dyno data, logged data and experience to develop this exhaust system, and the ECU remap that goes with it.
With the decat system and our purpose developed remap you can expect:
• 120bhp at the rear wheel. A gain of approximately 11bhp
• An exhaust note that compliments the bike perfectly.
• No exhaust drone anywhere in the rev range.
• A weight saving of approximately 2.6kg over the stock system.
• Improved throttle response and faster engine spool up.
• Smoother power delivery.
