A'PEXi - N1 Evo Extreme (Axleback) - 2022+ Subaru WRX (VB)

The A'PEXi N1 Evolution Extreme (N1-X) builds on the straight-through layout of the N1 muffler. An internal hybrid silencer balances flow with sound resonance, and the titanium tip is rolled and riveted onto a double-pipe structure that acts as a diffuser to reduce temperature, with a heat-gradation finish.
