REMARK R1-Spec Full Titanium Catback Exhaust - Subaru WRX (VB)
The REMARK R1-Spec Full Titanium catback is a single-exit exhaust for the Subaru WRX VB. Midpipe, muffler and tip are all titanium, so the complete system weighs about 7.3 kg (16 lb) with the resonator, roughly 10 kg (22 lb) lighter than the factory exhaust. It runs 76mm (3") mandrel-bent piping with no pie cuts, a high-flow straight-through muffler and a 114mm (4.5") slant-cut tip. REMARK rates the R1-Spec as louder than its other systems, so this is the loudest option in the range.

R1-Spec Full Titanium catback with resonator on a WRX VB
Two midpipe options are available. No Resonator (RK-C1076S-03TF) uses a straight midpipe for the loudest, most aggressive tone. With Resonator (RK-C1076S-03TFC) adds a resonator to the midpipe to bring overall volume down a step while keeping the same titanium layout.
Note: Suits the 2022-on WRX VB sedan with the 2.4L FA24F turbo engine. Even with the resonator, the R1-Spec is a loud, performance-focused system. Installation by a professional is recommended.
