10. With the short design and routing method of the Fuelies we've had no issues with dragging the pipes in a hard right turn. And while we were nervous about the end of the pipes not being secured to the bike or frame we haven't had any issues with excessive vibration or the pipes coming loose. The Fuelies have a nice rumble to them and we were afraid that they might be a little disrupting to our neighbors, but the inclusion of the baffles help give them a moderate tone while also providing some back pressure for improved performance.
