R1-Spec 中尾段排氣系統 - Subaru Impreza WRX / STI (GR 掀背) [08-14]

I installed this single-exit catback on my 2011 STI hatch and the track-ready tone is exactly what I was after. The welds and pipe routing look clean underneath, and the fitment was spot-on with no modifications needed.

My GR hatchback finally sounds like it means business. The single-exit setup is exactly what I wanted for track days, giving it that purposeful race-car note without being obnoxious on the highway.

The single-exit design frees up space under the bumper and looks properly aggressive. Paired with a downpipe, the sound is raw and race-inspired without being obnoxious on the highway.
