2022-2026 Subaru WRX 鈦合金 AFD F1 單出排氣管

The weight difference is wild—going from the stock muffler to this titanium single exit, the rear end feels noticeably lighter on turn-in. The F1-style tip gives it that raw, aggressive tone without being obnoxious on the highway.

The hand-crafted titanium really shows in the welds, and the single exit gives it that raw, track-ready sound I was hoping for. Dropped about fifteen pounds off the rear end, and the tone is deep without being obnoxious on the highway.

The sound on cold start is exactly what I wanted—deep and aggressive without being obnoxious on the highway. At 19 pounds, the single exit setup weighs less than my stock catback, and the titanium tips have already started to develop a nice blue tint from the heat.
