The history of the SuperTrapp muffler dates back to 1971 in the Davis, California garage of inventor, Paul Moller. In the late 60's, Moller was immersed in experimental trial of the XM-3, his early attempt at a flying automobile. In desperate need of funds, Moller began looking for an intermediate, far easier target for his newly developed tunable disc technology. Eventually Moller turned to a passion of his - motorcycles. And, the SuperTrapp muffler was born, soon becoming one of the most popular aftermarket accessories ever made for motorcycles.
