Invidia's R400 tuned muffler exhaust systems offer a rich exhaust note which enhances the natural tone of your car's engine. Invidia's high flow design ensures efficient exhaust flow for optimum engine performance.
Specifically designed to fill the sound gap between the Q300 and N1 system, the R400 produces a unique, aggressive exhaust tone without any harsh cabin noise (particularly at highway speeds).
This system features 3" (2.4" at the mufflers) FULL titanium piping throughout, with quad blue titanium 80mm (3.15") tips. The full titanium system saves a massive amount of weight!
The photo here shows a CAD rendering of the system; real product photos coming soon.
Fits all 2015-2021 Subaru WRX and WRX STI.
