Who knew the Clubman exhaust was 30 years old? or who really cared? Well Mark Broadhust apparently does and has devoted a lot of time and energy into the exhaust. It’s no secret that Mark and his company MBDevelopments have come up with many quality performance parts for the Lambretta over the years but man, talk about information overload! Check out this dyno chart and picture filled facebook post of the history of the exhaust, how he has gone about improving them, and a sneak peak at a new version being made in collaboration with Scooter Center Koln.
