2015-2021 Subaru WRX/STI AFD F1 鈦合金單出排氣管

The blue titanium finish looks even better in person than online, and it's so light I almost thought the box was empty. After a week of driving, the sound is deeper and more aggressive than stock without being obnoxious on the highway.

Bolted it on in about an hour with zero fuss, and the weight savings are immediately obvious when you lift it out of the box. The full blue titanium shifts color in the sun, but the real kicker is how the single exit wakes up the rumble without being obnoxious on the highway.

The blue titanium finish looks even better in person than in the photos, and the weight difference from the stock muffler is honestly shocking when you first pick it up. Bolted right on without any fuss, and the sound is deep and raw without being obnoxious on the street.
