Invidia Gemini R400 Cat-Back Exhaust 2011-2014 WRX/2008-2014 STI Hatch

Invidia's R400 tuned muffler exhaust systems offer a rich exhaust note which enhances the natural tone of your car's engine. Invidia's high flow design ensures efficient exhaust flow for optimum engine performance. No fewer than FOUR separate muffler canisters announce your car's presence in both looks and sound.

Specifically designed to fill the sound gap between the Q300 and N1 system, the R400 produces a unique, aggressive exhaust tone without any harsh cabin noise (particularly at highway speeds).

3" 304 stainless steel piping throughout, with quad 4" tips.  Choose between burnt titanium or polished stainless steel straight-cut exhaust tips.

Choose from stainless steel or titanium tips.

2011-2014 Subaru WRX/2008-2014 STI, hatchback models only. Does not fit sedan.
