Subaru STi Performance Exhaust - Invidia G5 Titan Titanium Cat-Back (2015–2027). A premium full-titanium system that cuts weight and delivers a crisp, motorsport-inspired tone for enthusiasts who want quality and response.

The G5 Titan series is crafted by Invidia from high-grade titanium for strength, heat resistance, and long-term durability. Mandrel-bent piping and a straight-through muffler path promote efficient flow, sharpening throttle response and revealing a distinctive turbo note. Precision TIG welds, CNC-cut flanges, and factory-style mounting points create a clean, bolt-on fit. The system ships ready to install with gaskets and hardware.
