Maniflow

David Dorrington started at the innovative Downton Engineering in 1962 and left in 1971 to form his own company (Maniflow). Developing and supplying parts to ex-Downton employees, who had started their own business (notably Richard Longman and Brian Slark).

Our products have been and are still used by many top teams from Formula 1 and Works teams to major manufacturers, all achieving championship status and international success, in fact virtually every branch of motorsport that requires gas-flowed tubular components. Consequently, over 40% of our products go overseas, making us one of the largest British classic exhaust producers, amply justifying the pride we take in the quality of our work.

All our manifolds and systems are manufactured to perfection; special attention is paid to all joints, welds, bends and Y section radii venturi, to create the correct back-pressures and ultimate gas-flow. We will not sacrifice quality for quantity.
