This Made My R9 INSANE (RaceFit Exhaust + Stage 2 DNA Filter + ECU Flash)

In today's video, I take my Yamaha R9 out for a quick pull with the RaceFit Exhaust, then jump into some major upgrades. I installed a Stage 2 DNA Air Filter and flashed the ECU with 2WheelDynoWorks to enhance the performance of the CP3 engine. I also replaced both my front and rear wheel to finish the setup. These mods completely changed how the R9 feels and sounds. Let me know what you think was it worth it? Follow me: Instagram & TikTok: edwins.r9
