I think if you have a bike they'll whinge about you anyway whether you have a race can/s or not.
  All I can say (being a person who lives in a quiet country village) to those folks is:  
GET A LIFE Whingers 
 Either that or get rid of your leaf blowers, lawnmowers, strimmers (especially petrol ones) chain-saws, hammer drills, hedge trimmers etc cos they all make more noise for longer periods of time in the community than a bike cruising thru on a Saturday afternoon.  
 How many times have you all been asked to turn off your noisy lawn-mower!!!!! 
 Having said that if the bike riders rev their engines as they go thru villages or roar thru in 1st gear at 30mph/6k-8k revs then they can only expect repercussions... 
 To me, there's more important things in life, but to some............... 
 
  Happy (non-eventful) riding peeps
