Invidia 11-14 Subaru WRX / STI Sedan Gemini/R400 Single Layer Quad Titanium Tip Cat-back Exhaust

This is the Invidia Gemini R400 Single-Layer Cat-Back Exhaust System. This exhaust system features a design that combines minimal bends with a larger piping diameter. This will allow for an unobstructed exit of exhaust gases with minimal restrictions and turbulence. This will allow for improvements in both horsepower and torque, along with improvements in throttle response. Additionally, the Gemini R400 will create a race-inspired exhaust note that will make the overall driving experience much more enjoyable.
