MCLAREN 620R - LARINI 'GTC' EXHAUST RACE PIPES (INCO)

Endurance/Competition/Race... Larini ‘GTC' Race Pipes are high temperature resistant INCONEL SHIELDED, hollow pipes, which replace the original bulky catalytic converters. The original lambda/heat probe connections are retained.

Exhaust flow is completely unobstructed through these 'pipe only' components. Temperatures are reduced too, as accelerated gas-flow minimizes engine-bay temperatures by dissipating heat more effectively. This is particularly important for improved performance, as cooler temperatures boost engine efficiency.

Furthermore, the muffling effect provided by the bulky stock cats is eliminated, enhancing volume levels.

For Off Road Use Only.

NB: Vehicles registered on or after 1st August 1992, are required to have a fully functioning catalyst fitted in order to comply with U.K. MOT test requirements. (Many other countries have similar requirements).

THERMAL MANAGEMENT -

Heat is a major issue in the back of any rear engined Supercar, and the McLaren is no different. The stock exhaust catalysts have a detachable outer skin with no thermal matting placed underneath. This Is Replaced With Superior Lightweight Inconel Shielding + Insulation (See Below).

** For ultimate performance, thermal management, AND DURABILITY, the Larini 'GTC' Race Pipes feature custom designed, double layer, INCONEL SUPERALLOY Dual Heat Shielding Technology (with internal performance insulation). Perfected through the racing programme & tested to destruction in the harshest of thermally volatile environments - this technology offers unrivalled, and SUSTAINABLE, vehicular exhaust performance. Little else comes close.

THE METHODOLOGY -

Bulky single skin exhaust shielding is used by OEMs to safely 'manage' engine bay temperatures. Larini evolves that application further to aid overall vehicular performance. Larini uses superior, lightweight, ultra-thermally efficient Inconel shielding to protect engine bay components from damage by the massive heat generated by the McLaren exhaust line. However, by Dual Shielding, keeping the lightweight inconel shield tight to the race pipe AND double insert-insulating the race pipe component, overall 'performance' now increases too... Keeping the heat within the race pipe by limiting external dissipation as much as possible, means the hotter the internal expelled exhaust gas is - the faster it flows - this is physical law. Faster expulsion of exhaust gasses results in less pressure backing up to the engine, and vitally- increased engine performance.

Dual shielding is an overtly complex and labour intensive technology to apply. Yet, Inconel Dual Heat Shielding Technology is the barrier favoured for use in F1 engine component packaging by Manufacturers - obsessed with chasing durability AND outright performance in the thermally volatile demands of the modern Turbo Charged/Hybrid era. Primarily, without doubt, as it is unlikely to fail to perform to an elite level, under prolonged and aggressive heat cycling. (It will not wear away or fall off, being durable enough to endure repeated physical handling and use under the pressure of competition).

PLEASE NOTE -

The use of heat-safe shielding is used on the stock exhaust catalysts themselves. Due to the internal packaging and critical operating temperatures of the McLaren, aftermarket unshielded large diameter exhaust race pipes may risk exposing the surrounding engine bay components to 'heat soak' damage. When replacing the catalysts on a McLaren - the driver must be sure of the credibility of the aftermarket thermal barrier on the race pipe component being used. A paint-based barrier IF not applied correctly, may not suffice as a longterm option in this instance. (Every thermal barrier has its place on the thermal spectrum - but must be rated accordingly and applied correctly, as per thermal requirements - many 2nd tier re-sellers tend to be unable or unaware of this as they rarely work on the project vehicles themselves).
