Fz-09 M4 Carbon Fiber Exhuast - Baffle Removed

Yamaha Fz-09 with the M4 Carbon Fiber Slip on exhuast. Removed the baffle about a year ago.

The microphone generally picks up the sound correctly, but the volume is what's missing. Without the baffle, this thing is borderline obnoxiously loud. Be advised.

The "cold start" wasn't fully cold. I took the short ride up to that reservoir, so don't worry about that revving.
