No, I can understand this....I've run a number of /6 BMW's and it'd seem like sacrilege to mess with the exhaust sound on these.
Again I've also run Guzzi California's and never felt the need to change from standard exhausts....
For me though the TBA does cry out to be freed up a little....though on my trip to France Belgium and Holland last week I was happy to be running as standard once the bike was opened up on the motorways.....
