Invidia [11-14 WRX/STI Sedan] R400 Gemini Quad Full Titanium Cat-Back Exhaust

If you're looking for the ultimate cat-back system on your WRX or STI, titanium is the way to go. With the material properties of titanium you can expect a system that is at least 50% lighter and more resistant to corrosion. The Invidia R400 Gemini Quad Full Titanium Cat-Back Exhaust features resonated 80mm (3.15-inch) mandrel-bent titanium piping feeding four individually muffled exits with quad single-layer 101mm burnt-blue titanium tips - the best combination of weight reduction and looks. This is a great performance exhaust without being extremely loud and obnoxious.
