Provides your WRX or STI with a Vicious Sound and Great, New Look

Your 2015-2020 Subaru WRX or STI may be a powerful street and track machine off the showroom floor, but the factory cat-back sure doesn’t let you or your competition know it. Invidia’s Gemini R400 Cat-Back for 2015-2020 WRX and STIs adds a brutal, aggressive exhaust note to your wicked Subaru build that is sure to turn some heads on the street, autocross course, or drag strip. The Invidia Gemini R400 replaces your Subie’s quiet chambered mufflers with quad straight-through designs that let your track-ready WRX or STI sing at full volume without restrictions. Best of all, the Gemini R400 comes with a choice of tip finish so that you change up your WRX or STI’s looks while getting a whole new sound.

Smooth-Flowing, 76mm Tubing with 304 Stainless Steel Construction

Invidia’s R400 Gemini Cat-Back changes up your Subie’s looks and feel in a high-quality package. Each system is made out of 76mm, mandrel-bent tubing that provides smooth exhaust outflow to help support other power-adders and custom tuning. The system is manufactured entirely out of SUS304 stainless steel with a gorgeous polished finish that will make your 2015-2020 WRX or STI look classy at your local meet or at the track. The four angled tips are each 101mm diameter and are available in your choice of standard polished 304 stainless steel, blued titanium, or black finishes so that you can match your WRX or STI’s styling theme or paint color. The Invidia R400 cat-back installs right into place of your Subaru’s stock exhaust without the need for any cutting or trimming. Invidia backs their R400 Gemini System with a 1-year limited warranty.
