Akrapovic is the only company that BMW will continue to honor for warranties. All others can be just cause
to not honor under warranty if it is proved to be the cause of the problem. O2 sensor, valves, fueling, ECU, etc.
Having said all that, I ran a non approved slip on muffler (Leo Vince) on my K1200 GT, never an issue.
Most modern ECU's can self adjust modest changes to exhaust back pressures. I doubt that removing the
baffle will change much other than a little noise difference.
