Fabspeed Sport Cats with GT2 RS Style Outlets for 992.2 Porsche 911 Carrera & Carrera S

Fabspeed’s Sport Cats with GT2 RS Style Outlets for the 992.2 Porsche Carrera and Carrera S are engineered to deliver maximum power and sound without triggering check engine lights. This system emulates the valves-open configuration of a 991 GT2 RS, unleashing a significantly louder, more aggressive exhaust note with pronounced turbo spool, sharper burbles, and harder pops on deceleration. Thanks to a modular design, owners who find the setup too loud for daily use can add optional muffler adapter pipes to reinstall the factory rear muffler or pair it with Fabspeed’s Valvetronic Maxflo Exhaust, creating a flexible, GT2-inspired solution that matches the performance and speed of the 992 Carrera.

Power

• Fabspeed’s system represents the most free-flowing exhaust design possible while still retaining catalytic converters. Testing on their AWD Dynojet showed gains across the entire rev range: at 3000 rpm, the turbos spool faster and harder, adding 23.7whp and 41.5ft-lbs of torque, while peak gains at 5300 rpm reached 47.7whp and 47.1ft-lbs of torque, equivalent to roughly 54hp at the crank. A detailed dyno graph illustrates the improvements throughout the powerband.
