Experience a dramatic performance and sound transformation with these Porsche 992 GT3 200-cell Inconel Manifolds (NON-OPF). Designed for maximum flow and optimal acoustics, this system replaces the restrictive 600 CPSI catalytic converters and OPF filters found in the factory exhaust. By eliminating these limitations and incorporating high-flow technology, the engine delivers a sharper, louder, and more aggressive tone.

The lightweight Inconel 625 construction provides exceptional heat resistance and contributes to the unique high-frequency resonance associated with premium motorsport exhaust systems. Its thin wall design enhances exhaust pitch, producing a clean, razor-sharp tone at high RPM.

Airflow is further optimized through the free-flow valve-open path, while the valve-closed route uses a harmonically tuned silencer designed to eliminate cruising drone. The signature tight-radius X-pipe raises exhaust pitch and creates a distinctive, high-energy scream without restricting gas movement.

The largest power gains come from replacing the stock catalysts and OPF system. These manifolds are engineered to work seamlessly with the matching Kline silencer section. Two performance configurations are available:
• 100 CPSI high-flow catalysts offering gains up to 25 HP and 32 Nm
• Decat long-tube headers offering gains up to 31 HP and 38 Nm

This system delivers improved throttle response, reduced backpressure, enhanced acoustics, and a true race-bred exhaust character for your Porsche 992 GT3.
