Fi EXHAUST F1 Version Valvetronic Exhaust System for 991.1 Porsche 911 Carrera / 4 / S

Fi EXHAUST F1 Version Valvetronic Exhaust System for 991.1 Porsche 911 Carrera / 4 / S

Fi EXHAUST offers high-performance valvetronic exhaust systems for the Porsche 991.1 Carrera, Carrera 4, Carrera S, and Carrera 4S F1 Version, available in both T304 stainless steel and signature titanium versions. Designed as direct bolt-on replacements, these systems enhance sound, performance, and torque while delivering an exhilarating driving experience. The T304 stainless steel system optimizes airflow, adjusts sound volume, and increases torque. Installing a full system—including a valvetronic catback and an ultra-high flow downpipe—can boost horsepower by 5-10%. The signature titanium exhaust reduces weight by 46% compared to stainless steel while maintaining exceptional strength. Every component, including valves, clamps, and screws, is crafted from titanium for maximum durability. The 1.6mm-thick pipe walls improve exhaust frequency, increase durability, and extend lifespan. A polished interior and exterior further enhance exhaust gas flow and refine the sound note. Both versions feature valvetronic technology to control airflow and sound. With valves closed, exhaust gases are routed through the muffler for a refined and comfortable drive. When fully open, the system delivers an intense and exotic soundtrack.

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.

Fi EXHAUST Pro Control System

• The Fi EXHAUST Pro Control System includes an intelligent control box, a two-button remote, and a mobile app. The app prevents CELs, monitors valve status, and enables Auto Mode based on RPM, speed, or boost. The remote allows precise valve control, while its customizable aluminum or forged carbon design offers style and functionality.
