Perfect road tuned exhaust suitable for all Lambretta LI (series I-III) and DL/GP models. Compatible with the original cylinder exhaust outlet and also available for race cylinders.

Box-style exhausts have been popular on the Vespa scene for quite a while now. Recently, these inconspicuous exhausts systems have enjoyed increased use amongst Lambretta tuners. Their use on Lambretta models has tradition, with the first aftermarket concepts appearing as early as the 1960's. The most well known amongst them must be the 'Clubman' box system. The boom in the Vespa sector of the market has led Lambretta parts producers to rediscover these exhaust systems and invest time and money to bring them more up to date. Although an increase in performance for these pipes used to mean only the dimensions of the manifold section would be altered, these newly produced types possess carefully calculated conical manifold sections. These have the welcome effect of noticeably improving the exchange of gases in the cylinder.
