R1-Spec Catback Exhaust

The Remark R1 Spec Single Exit Catback is a lightweight, aggressive exhaust option designed for WRX owners prioritizing raw sound and weight reduction. Featuring a full 3” stainless steel design, this system eliminates the traditional dual-exit layout in favor of a single-exit configuration, reducing weight and simplifying flow for a more direct, race-inspired feel. Unlike muffled systems, the R1 Spec is essentially a straight-through design with minimal sound suppression. This results in a very loud, sharp exhaust note with pronounced turbo sounds, pops, and crackles—especially under load and during deceleration. It’s one of the loudest off-the-shelf options for the VB WRX, making it better suited for enthusiasts who want maximum presence rather than daily comfort. The single-exit layout also gives the car a unique, track-style aesthetic, though it leaves one side of the rear bumper empty unless paired with a block-off plate or diffuser solution.
