Maximize exhaust flow and unlock the aggressive sound of your Porsche 991.2 Carrera with the Fabspeed Competition Link Pipes. Designed specifically for the 2017–2019 Porsche 911 Carrera equipped with the standard factory exhaust system, these high-performance competition pipes replace the original catalytic converters with free-flowing stainless-steel tubing for reduced exhaust restriction and improved performance potential.
Porsche's 991.2 Carrera introduced a 3.0L twin-turbocharged flat-six engine, making exhaust efficiency an important consideration for performance-oriented builds. By eliminating the factory catalytic converters, the Fabspeed Competition Link Pipes reduce exhaust backpressure downstream of the turbochargers, allowing exhaust gases to flow more freely through the system.
Fabspeed advertises performance gains of 17 horsepower and 16 lb-ft of torque for this product, along with approximately 3 pounds of weight savings compared with the original catalytic converter assemblies. Actual performance improvements will vary depending on vehicle condition, engine calibration, supporting modifications, and operating conditions.
The straight-through design also produces a substantial change in exhaust sound. Removing the catalytic converters increases exhaust volume and allows more of the engine's natural turbocharger and flat-six exhaust characteristics to be heard. Drivers can expect a more aggressive exhaust note, particularly during acceleration and high-RPM operation.
Manufactured from 0.065-inch-thick T304L stainless steel, the Fabspeed Competition Link Pipes are engineered for durability and resistance to the elevated temperatures generated by Porsche's turbocharged engine. The high-quality stainless-steel construction provides excellent corrosion resistance while maintaining a lightweight, performance-focused design.
Each assembly is designed and manufactured in-house at Fabspeed's precision machining facility. The pipes feature integrated oxygen sensor bungs to accommodate the vehicle's factory exhaust oxygen sensors while maintaining the appropriate sensor mounting locations.
The system is engineered as a direct bolt-on replacement for the factory catalytic converter assemblies on compatible non-PSE Carrera models. Installation does not require cutting or welding when used with the appropriate exhaust configuration.
One of the most important fitment considerations is the vehicle's original exhaust system. Part number FS.POR.9912.CB is designed for base Carrera models equipped with the standard exhaust, not Porsche Sport Exhaust (PSE). Carrera S applications require a compatible complete exhaust package rather than using these pipes as a standalone direct replacement.
The Fabspeed Competition Link Pipes are intended exclusively for dedicated competition vehicles operated in closed-course racing environments. They are not certified for emissions-controlled public-road use and should not be installed on vehicles required to retain their original emissions equipment.
For Porsche 991.2 Carrera owners building a dedicated track or competition vehicle, the Fabspeed Racing Cat Bypass Pipes provide lightweight stainless-steel construction, reduced exhaust restriction, improved performance potential, and an aggressive exhaust sound.
