Specs & Features
The Invidia Gemini R400 catback is one of the most popular Subaru WRX and WRX STI exhaust upgrades for the 2015-2021 platform. It is a direct bolt-on setup built from 3" SUS304 stainless steel with mandrel bent piping and CNC machined flanges. All necessary hardware, bolts, and gaskets are included. This is a catback system and does not alter, remove, or replace any emissions equipment.
The R400 is specifically designed to sit between Invidia's Q300 and N1 systems in terms of sound. It gives the WRX and STI a deep and aggressive exhaust note without being overbearing at highway speeds. The exhaust opens up more at wide open throttle while staying clean and controlled at cruise.
If your car is still running the stock downpipe or J-pipe, you will need the GrimmSpeed stock downpipe to 3" catback adapter for this system to fit properly. That adapter is sold separately.
The system is available in three tip styles, each with its own part number listed below.
