Fi Exhaust Catless Downpipe + Valvetronic Muffler (Retains OEM Valve Settings - No Remote) - Porsche 991.2 GT2 RS 2017-2019 (80mm Full FI Version)
Experience the full potential of your Porsche 991.2 GT2 RS with the Fi Exhaust Catless Downpipe + Valvetronic Muffler (80mm Full FI Version). Engineered for maximum performance and OEM-level integration, this system replaces restrictive factory components with a free-flowing, precision-built setup designed for serious enthusiasts.
The catless downpipe dramatically reduces backpressure, allowing the 3.8L twin-turbo flat-six to spool faster and breathe more efficiently. The result is sharper throttle response, increased mid-range power, and an unmistakably raw motorsport tone. Constructed from high-grade stainless steel and welded with race-spec precision, the downpipe is designed to withstand extreme thermal loads typical of GT2 RS driving.
Paired with FI’s 80mm full valvetronic muffler, this system retains OEM valve control—giving you factory-style switchability with a far more aggressive sound profile. Closed valves maintain a refined, manageable tone for street use, while open valves unleash a thunderous, high-flow exhaust note with amplified turbo acoustics.
This Full FI version features enlarged 80mm piping throughout, ensuring optimal flow for tuned and high-demand applications while maintaining perfect fitment and compatibility with factory sensors and valve actuators.
