Fi EXHAUST Valvetronic Exhaust System for 8S Audi TT RS (facelift)
Fi EXHAUST introduces a high-performance valvetronic exhaust system for the Audi MK3 (8S) TTRS 2.5T Quattro Facelift, designed as a direct bolt-on replacement. Constructed from high-grade T304 stainless steel, this system delivers an exhilarating soundtrack while enhancing overall performance. Engineered with advanced valvetronic technology, the Fi EXHAUST system optimizes airflow, regulates sound volume, and improves torque. A full setup, including a valvetronic catback and ultra-high flow downpipe, can increase horsepower by approximately 5-10%. With the valves closed, exhaust gases are routed through the muffler for a refined and comfortable driving experience. When fully open, the system produces an intense and sporty exhaust note, elevating the driving experience.
