Gemini R400 Cat-Back Exhaust System

The Invidia Gemini R400 Full Titanium Cat-Back Exhaust system is engineered as Invidia's premium offering for the 2015-2021 Subaru WRX (FA20DIT) and STI (EJ257) VA chassis. Constructed entirely from titanium, this cat-back exhaust significantly reduces rear-end weight compared to stainless steel alternatives. It features 80mm diameter primary piping which elegantly splits to 60mm at the Gemini muffler connections, designed to complement the exhaust volume requirements of modified VA platform engines. The system is visually striking with quad 101mm round titanium exhaust tips and a straight exit orientation. Included in the box are the full titanium cat-back exhaust system, titanium exhaust tips, gaskets, and all necessary mounting hardware. Invidia has been manufacturing performance exhaust systems in Japan since 1999, utilizing SUS304 stainless steel and mandrel-bent tubing for optimal flow and durability. Their application-specific designs ensure a precise fit and clean installation. This exhaust is specifically designed to fit the 2015-2021 Subaru WRX with the FA20DIT engine and the 2015-2021 Subaru WRX STI with the EJ257 engine, both on the VA chassis.
