Paul Dunstall was famous in the late 60s and 70s.
Starting with Nortons,
Breathed on a bit and lots of after market goodies, as the British industry closed down he started doing bits for Japanese bikes,
He was famous for his tapered meggas, an alternative to the Goldie pipes for cafe racers,
They seemed ok at the time,
