Description

The GrimmSpeed Un-Resonated Cat-Back Exhaust for the 2011-2014 Subaru WRX Hatchback and 2008-2014 Subaru STI Hatchback is the louder, race-inspired counterpart to the resonated 070045. With no internal resonators, this hand TIG-welded 304 stainless steel cat-back delivers a more open, aggressive exhaust character - the choice for builds where maximum sound character takes priority over daily refinement. Hatchback models only.
