Fi Porsche 992 GT3 / RS | 2021+ Race Version Exhaust (CATLESS)

Exhaust Fitment:

Exhaust System Components:

This exhaust system package includes the following components:

• Catless Header + Valvetronic Muffler

Crafted from high-grade T304 stainless steel, this direct bolt-on Race Version system delivers a raw, motorsport-inspired soundtrack that fully complements the Porsche 992 GT3 RS high-revving nature.

Engineered as a complete replacement for the factory exhaust, the system restores exhaust flow and reduces backpressure—resulting in sharper throttle response, improved mid-range torque, and more linear power delivery across the rev range.

With a full catless configuration, including long-tube headers and a high-flow X-pipe muffler, the Race Version delivers dyno-proven gains of up to +25 WHP without ECU tuning.

The system reuses factory valve actuators, allowing seamless integration with OEM drive modes—offering controlled operation during low-speed driving and an aggressive, race-bred sound when fully opened.

By eliminating restrictive emissions components, the engine breathes more freely, unlocking sustained performance from mid-range to redline while significantly reducing overall system weight.

As a full Race Version setup, removal of OPF/GPF filters or catalysts may trigger a Check Engine Light without the use of a simulator or ECU solution.

Availability may vary depending on your vehicle configuration—please refer to the add-on section or consult our team for confirmation.

Behind the performance lies a motorsport-driven design, engineered to deliver an uncompromised, high-pitch sound and driving experience worthy of the GT3 RS.
