A'PEXi was founded in April 1992, and began with exhaust systems, including its N1 range. It was one of the first to offer a complete engine computer that replaced the factory one, the Power FC, made to fit each engine and simple to adjust.
A'PEXi raced in Super GT and won the D1 Grand Prix championship in 2003 with an RX-7. Its range covers intakes, exhausts, engine management and boost control, and suspension, for most Japanese performance cars.
