Add a trumpet to your tailpipe

This tail-pipe hack is meant to make some noise every time the vehicle (in this case a motorcycle) spits out enough carbon monoxide that could be harmful to the environment. Since this might end up getting you into an accident, so we don’t condone this type of modification, still it’s kind of nice to hear the sound of trumpets rather than the usual gas guzzling motor sounds your bike normally spits out.
