Its incredibly quiet and still provides lots of power when derestricted. Fyi the exhaust comes restricted and means removing the spot welds found in the mainfold end. There is a large restrictor pipe that then comes out when the welds are removed. Use a dremmell to get them out. Its a bit of a pain but makes considerable difference when done. This replaced a sito plus exhaust and is pretty much equal in power.

Massive improvement on my little 50cc Vespa over the original, broken exhaust.
