Fi EXHAUST Valvetronic Exhaust System for 991 Porsche 911 GT3 / RS

The Porsche 991.1 GT3 / RS Fi EXHAUST is a high-performance valvetronic system engineered as a direct bolt-on replacement, crafted from high-grade T304 stainless steel or lightweight titanium to enhance torque, airflow, and sound control. With a full setup—including a valvetronic catback and ultra-high-flow downpipe—horsepower gains of 5-10% can be achieved. Closed valves provide a refined, comfortable drive, while fully open valves unleash an intense, sporty exhaust note. The Fi EXHAUST Titanium for Porsche 991.1 GT3 / RS offers a lightweight alternative, reducing weight by 46% compared to stainless steel while maintaining strength and durability. Every component, including valves, clamps, and screws, is made from titanium to optimize weight savings. With 1.6mm-thick polished titanium walls, it enhances exhaust sound frequency, gas flow, and aesthetics. Integrated valvetronic technology ensures seamless control, offering a low-profile tone when closed and an intense, exotic soundtrack when fully open.

Valve

• Fi Exhaust systems universally incorporate valvetronic technology, enabling precise sound control while boosting vehicle performance. Prior to this innovation, achieving both high torque at low RPMs and greater horsepower at high RPMs was challenging. Valvetronic technology resolves this contradiction, allowing sports cars to excel in both areas and delivering a balanced yet dynamic exhaust performance.
