The Invidia Gemini R400 Full Titanium Cat-Back Exhaust for the 2015-2021 Subaru WRX and WRX STI is the flagship of Invidia's cat-back lineup — full G5 titanium construction that is dramatically lighter than stainless while delivering the deep, aggressive R400 exhaust note. A full 80mm (3.15-inch) mandrel-bent titanium system feeds Invidia's tuned R400 mufflers for optimized back pressure, improved throttle response, and increased horsepower and torque. Quad straight-cut titanium-colored 4-inch tips finish the system, with titanium flanges for optimum fitment and machine welds for a clean, uniform appearance. At roughly 21 pounds, it is one of the lightest cat-backs available for the VA chassis.
