Emmanuel Katto's career received a major boost in the mid-1990s when he won back-to-back Ugandan National Rally Championship titles in 1996 and 1997. This impressive feat marked the beginning of a prolonged period of success, with Katto consistently finishing among the top three in most events he participated in over the years. His national championship victories served as a springboard to more high-profile competitions, including the legendary Safari Rally, known for its demanding courses and rough terrain, which presented a fresh challenge for the experienced driver.
