How to Increase the C6 turn signal tic tic tic

I really like the new (to me) C6 but the turn signal sound (tic tic tic)
is so low it is just about useless. Its there something like an old
fashion flasher relay that can be changed to increase the sound level of
the tic tic tic. It is swamped out by the engine and dual mode exhaust.

Are the all low or is low tic tic tic sound mean something is wrong with
mine?
