I have two bikes, an '08 Tuono with aftermarket exhausts (Akrapovics) and an '07 FZ6 with stock exhausts. So I come home the other day from work on the FZ6 and walk into the kitchen from our attached garage, scaring my wife. She says "I didn't hear you come home!" I explained that my Yamaha has stock exhausts, unlike my Aprilia, so she says "You should buy some new exhausts for that bike so cars can hear you." Guess it's time to do some shopping....:thumbup:
