After the big success of the Lambretta Big Box we asked Mark Broadhurst if he can’t work his magic into a Vespa exhaust as well. Like the Lambretta Big Box the volume of the Vespa one was enlarged as well. This gives a standard looking exhaust that performs even better as some expansion chambers.

One of the nice things is that the Vespa Big Box works on all engine setups and that you don’t have to suit the port timings of your engine to the expansion chamber you use. At it is the case with the latest expansion chamber development. Simply put the Big Box under your Vespa and it should rev better and accelerate faster.
