The Apexi Active Tail Silencer features an anti-pressure response valve to decrease exhaust volume. The 'Active' Tail Silencer opens as the pressure increases to provide free high flowing exhaust flow when power and torque is required but reduces volume through restriction during times of low pressure. These features help to reduce noise when required but not hinder performance when desired.
Features
- Automatic valve operation based on pressure from vehicle
- Inner structure reduces exhaust resistance with high revolution
- High quality iconel spring used for superior heat resistance.
- Ball plunger type valve

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.
