BMW R Nine T has a refined and impressive sounding horizontally opposing twin cylinder engine, but as with most enthusiast vehicles, we want more! In this video, I’m doing my first mod on the bike and the goal is to make the exhaust sound just a little louder and better. I’m removing the DB killers from the Akrapovic mufflers which gives the exhaust note a throatier sound and a lot more depth. I show how to remove the DB killers (exhaust baffle) and the the different of how it sounds before and after giving you more sound for free.
