Invidia 2009+ WRX/STi Sedan G5 Titan Titanium Cat-Back Exhaust
The Invidia G5 Titan Exhaust is the apex of Invidia’s engineering—a no-compromise, full titanium system that balances cutting-edge motorsport design with street-worthy refinement. Crafted from aerospace-grade titanium, the G5 Titan delivers one of the lightest, most responsive catback exhausts on the market, aimed squarely at hardcore drivers and track warriors looking for every performance edge.
What sets the G5 apart is its meticulous construction. Each piece is hand-welded with precision, using ultrathin yet strong titanium piping to minimize weight and maximize flow. On average, the G5 Titan shaves off up to 40% of the weight compared to stainless steel systems, dramatically reducing rotational and unsprung mass for sharper handling and quicker throttle response. The system’s layout is engineered for optimal exhaust velocity, improving scavenging and boosting mid-to-high RPM power.
The G5 Titan isn’t just about numbers—it delivers an unmistakable titanium tone: a sharp, high-pitched, exotic note that grows with RPM, echoing the sound of true racing heritage. It’s race-ready but refined enough for spirited street driving. Thanks to Invidia’s internal resonator design and straight-through layout, the system balances volume and clarity without overwhelming drone.
Visually, the G5 Titan stands out with its signature burnt blue tips, CNC machined flanges, and premium welds—each one a mark of craftsmanship. For those who demand the ultimate in performance, looks, and sound, the G5 Titan is Invidia’s magnum opus.
