Exhaust Kit — Subaru WRX STI VAB, Subaru WRX S4 VAG

An exhaust kit developed to provide a sense of unity with the vehicle for performance-oriented WRX STI/S4 owners. Based on the muffler standard-equipped on the STI special specification model "S207," it has been appropriately tuned for standard vehicles. To sharpen engine response to throttle operation, back pressure has been reduced by over 40%, aiming for improved acceleration performance noticeable during starts and acceleration out of low-speed corners. Additionally, the slash-cut tailpipes (101.6φ × 2 per side) enhance the rear view's impact while adding a premium touch, and through STI's unique tuning, a safe and reliable structure that does not affect the engine has been adopted. The exhaust sound tuning has also been carefully crafted to achieve a premium and pleasant sound befitting the character of the WRX STI/S4.
