Invidia adds more heat to their 2011-2014 WRX / STI line up with the Gemini R400 exhaust. The quad muffler design provides an aggressive look, while optimizing back pressure, increasing horsepower and torque, with a deep, menacing sound. The double wall titanium tips, mandrel bent SUS304 stainless piping, and TIG welding furthermore add to the exhausts beautiful appearance.
Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
Have a listen to the amazing exhaust note on the R400!
