For each pipe, we recorded mp3 clips for the sound testing and dyno testing portions. In the sound test, the bike was started, run at idle for a few seconds while sound was recorded, run at 6000rpm in neutral for several seconds, and then run at 60mph in fourth gear. These clips run approximately one minute in length, and about 600kB in size.
The dyno run clips are approximately 30 seconds in length and 300kB in size, and cover one full dyno pull.
