It sounds like they leaned it out for whatever reason, but I assume to meet emission tests. Hopefully no VW engineers worked on this part of the BMW program!
Jetspeed - If you put the aftermarket exhaust on the bikes at the dealer, do they then add an "update" to change the fueling map? Usually, with other makes, if a new silencer is added that further leans out the FI, the dealer will have a new map to go along with the change......
