There is no shared platform with any other manufacturer. No borrowed block from Mercedes or BMW. This is McLaren's engine, purpose-built for mid-engine supercar duty. The family splits into two generations: the M838T 3.8-liter that powered everything from the 12C to the 600LT, and the M840T 4.0-liter that brought the 720S and 765LT into 700+ HP territory.

The McLaren M838T 3.8-liter twin-turbo V8 is the engine that defined the modern McLaren era — powering the 570S, 570GT, 540C, 650S, and MP4-12C. These mid-engined supercars produce extraordinary power from the factory, but the restrictive catalytic converters downstream of each turbocharger leave significant performance on the table. Replacing the factory downpipes is the single most effective bolt-on modification you can make to the M838T platform.This guide covers everything you need to know about upgrading the downpipes on your McLaren: catless race downpipes versus high-flow catted options, real-world power gains, exhaust sound transformation, fitment across the entire M838T lineup, installation...
