How fast can your bicycle go? Why, that question can only be answered depending on how fast you pedal, and whether the direction which you are going in is uphill or otherwise. Well, for those who feel that they want an illusion of speed, you cannot go wrong with the tacky $15.99 Exhaust Pipe for Bicycles. The name says it all – it helps your bicycle look souped up, and equipped with a trio of sound chips, you will be able to have your bicycle emit different sounds as you roar down the street. Good thing there is no need for any batteries, as the Exhaust Pipe for Bicycles relies on air to rock and roll. Why not get a pair if you have a need for speed?
