Invidia [11-14 WRX Hatch] [08-14 WRX STI Hatch] Gemini R400 Cat Back Exhaust - Stainless Steel Tips
The Invidia Gemini R400 fills the gap between the mild Q300 and the loud N1 - a rich, aggressive note with no harsh cabin drone at highway speeds. Built from mandrel-bent 76mm SS304 stainless piping with cast flanges and tuned mufflers, it delivers Invidia's claimed gains of 17hp and 26 lb-ft of torque. Quad 101mm straight-cut stainless steel tips finish the system, which bolts to the OEM hanger locations with new gaskets and hardware included.
