It has only been on very rare occasions that I have seen twin or single cylinder four-stroke bikes, which were both quiet and extremely fast.

Before the longer Dunstall mufflers with the "ray gun" exits, Dunstall sold a shorter muffler that I think was actually a Wassell muffler which had a larger inside diameter tube made of perforated metal with a center perforated disc which we knocked out. The Contis had a similar shape and length. Those Wassell-Dunstalls, in my opinion were the best. Loud but powerful. We had to use a bushing to step down to the stock head pipe outside diameter.
