That part about the mufflers “silencers” changing colors suited to the type of riding that’s done sounds a lil...hawdabeeleeve! The part about how the exhaust is tuned for sound (is) believable though as Kawasaki did the same to my Z900RS. On mine, the volume and ’bark’ of the exhaust is dealt with in the breadbox sized Cat under the bike. Several guys have changed mufflers with almost no change in volume or tone. Once the Cat is deleted the baffling of the mufflers determines the sound but, it doesn’t change colors.
Thin walled headers can change colors but I’ve never seen a muffler change colors. It will be interesting to see how ‘each rider can add a unique personal touch to their bike’ by the different colors and “hue” of the silencers. Whaaaaa?
