The F355 Challenge shares the same engine tuning and physical dimension specifications as the original. Horsepower is up slightly owing to the free-flowing non-street-legal racing exhaust kit. 108 were produced, all with the 6-speed transmission (except for 1 that was equipped with a F1 gear box for a handicapped client).[citation needed] There were 18 RHD cars imported by Ferrari UK and modified by MHT. Some of these rare cars have now been converted to be street legal. Each F355 Challenge has an emblem on the rear that specifically denotes ‘F355 Challenge’.
