APEXi Active Tail Silencer

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
