Remark SS Quad Tip (Non-Resonated) Catback Exhaust - Subaru STi GR Hatch 2008-2014Our quad tip catback for the GR hatchback is a 3" catback design. Features a large single high flow muffler canister, and 3" mandrel bent piping. The 3. 5" tips are single wall construction, and feature a slant cut design which we feel suits the OEM bumper very well. The inner tips are longer, while the outers are shorter in length to better fit the shape of the rear bumper. Important This will only fit models that have the dual exit, quad tip OEM
