Vertex Sports Cat-Back Exhaust System

The Ganador GDE-408ST represents the Vertex Sports line of performance exhaust systems, specifically engineered for the Impreza Sport 2.0 with model years H28.10~ (GT7/GT6 chassis). This rear-piece replacement exhaust features a distinctive left-and-right, four-outlet configuration, highlighted by 85mm diameter titanium tail tips with a blue gradation finish. The design aims to not only enhance the vehicle's aesthetics but also unlock greater performance potential. Ganador states this exhaust system can deliver a notable increase in horsepower and torque, citing internal data showing a gain of 9.3 ps and 0.9 kgf・m (with a peak difference of 3.2 kgf・m at 2,800 rpm). Furthermore, the system is claimed to improve fuel economy by up to 12.0%, contributing to more economical driving. The exhaust produces a sound level of 85 dB at proximity (compared to the stock 79 dB), described as a gentle, comfortable low frequency that complements the FB20 engine's characteristics. Despite the increased sound, it is certified to meet vehicle inspection standards. Constructed with a focus on both form and function, the GDE-408ST incorporates Ganador's P.B.S. (Power Bouncing System) technology, featuring internal spiral fins within the muffler for performance enhancement. The titanium tail sections are finished with a visually striking blue gradation, transitioning from blue to gold when heated, adding a sporty flair. The system is designed with specific considerations for the GT7 bumper shape and includes a wool-less silencer for optimal performance. Installation is estimated to take 0.5 hours.
