Maximize exhaust flow and unleash the aggressive sound of your McLaren 570S, 570GT, or 540C with the Fabspeed Competition Link Pipes. Engineered specifically for McLaren's 3.8L twin-turbocharged M838T V8 engine, these high-performance downpipes replace the four restrictive factory catalytic converters with straight-through stainless-steel piping for improved turbocharger response, increased horsepower, and a dramatically louder exhaust note.
By eliminating the factory catalytic converters, the Fabspeed Competition Link Pipes significantly reduce exhaust restriction immediately downstream of the turbochargers. This freer-flowing design allows exhaust gases to exit more efficiently, helping improve turbocharger spool characteristics, boost response, and overall engine performance.
Fabspeed reports dyno-tested gains of 33 wheel horsepower and 22 lb-ft of torque with its Racing Cat Bypass Pipes. These improvements demonstrate the performance potential of reducing exhaust backpressure on McLaren's twin-turbocharged V8 platform. Actual results may vary depending on vehicle condition, calibration, and supporting modifications.
The exhaust note becomes substantially more aggressive with the factory catalytic converters removed. Drivers can expect increased turbocharger whistle, pronounced pops and crackles during deceleration, and sharp exhaust reports during upshifts. Fabspeed also notes that some interior drone may occur, making this system best suited for owners prioritizing maximum exhaust sound and performance.
Manufactured from 14–16 gauge T304L stainless steel, the bypass pipes feature CNC mandrel-bent tubing designed to maintain consistent internal diameter and promote efficient exhaust flow. Precision investment-cast inlet and outlet connections further optimize exhaust gas movement while ensuring proper alignment with compatible factory exhaust components.
The system also incorporates high-temperature exhaust heat blankets to help manage radiant heat within the McLaren's tightly packaged engine compartment. Each blanket features approximately 13mm of ceramic fiber insulation rated to 1,800°F, reinforced with stainless-steel mesh and protected by a durable basalt fabric exterior.
Fabspeed advertises approximately 10 pounds (4.4kg) of weight savings compared with the factory catalytic converter assemblies. The reduced weight complements the improved exhaust flow and performance-oriented design.
Designed for direct bolt-on installation, the Competition Link Pipes do not require cutting or welding. They can be paired with compatible factory rear exhaust components or aftermarket rear exhaust systems designed for the same vehicle applications.
The Fabspeed Competition Link Pipes are intended exclusively for closed-course competition and dedicated off-road racing applications. Because the system removes the factory catalytic converters, a check-engine light is expected on OBD2-equipped vehicles, and the product is not approved for use on emissions-controlled public roads.
For McLaren owners building a dedicated competition vehicle, these bypass pipes deliver substantial exhaust flow improvements, aggressive sound characteristics, premium stainless-steel construction, and integrated thermal protection.
