MCLAREN 620R - LARINI 'GT1' EXHAUST ASSEMBLY (INCO)

** For ultimate performance, thermal management, AND DURABILITY, the GT1 Assembly features 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 turbo charged exhaust. However, by Dual Shielding, keeping the lightweight inconel shield tight to the exhaust tubes AND double insert-insulating the exhaust component, overall 'performance' now increases too. Keeping the heat within the exhaust 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 allowing faster turbo spool up, reduced turbo lag, 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 extensive heat-safe shielding on the OEM Sports Series exhaust line - while helpfully detachable and reusable on the catalysts, is not so on the rear exhaust system. Conversely, extensive heat-safe shielding is welded directly onto the rear exhaust box itself. This is presumably due to the tighter engine packaging of the smaller Sports Series cars (unlike the physically larger Super Series cars where the rear exhaust is insulated by externally mounted single skin shielding e.g. 720S). Due to the internal packaging and critical operating temperatures of the Turbo charged Sports Series cars, an aftermarket unshielded large diameter rear exhaust may risk exposing the surrounding engine bay components to 'heat soak' damage. When replacing the rear muffler on a Sports Series McLaren - the driver must be sure of the credibility of the aftermarket thermal barrier on the exhaust 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).

The Larini philosophy is that the sporting vehicle must be super light. The key enemy for vehicle efficiency and dynamics is weight. Performance is not solely a number of horsepower - as power to weight ratio is equally important. Developed via racing, Larini's technologically advanced lightweight designs, unique sounds, and elite constructions, will assist the driver and vehicle to perform in the most demanding of environments. Whilst still satisfying those enjoying their super sports car on a regular basis.
