The PERRIN dual-tip axle-back exhaust fits 2015–2021 Subaru WRX STI and 2015–2025 WRX applications and is designed to work with OEM or aftermarket center pipes. Offered as a rear-section axle-back system with dual tips, the unit replaces the factory axle-back to change sound and flow characteristics while fitting to existing center-pipe connections, providing a direct rear exhaust swap for compatible Subaru models.
