McLaren 765LT / 765LT Spider V8 biturbo Valved Exhaust System (2020-2023)

The McLaren 765LT / 765LT Spider exhaust in detail.

The 765LT is the most extreme McLaren of its line: 765 hp and 800 Nm, obsessive weight saving and titanium exhaust outlets passing through the rear deck. A car like this deserves a voice to match. Our page covers the 2020 to 2023 model years; the 720S and 750S have their own systems, and your VIN lets us check compatibility before manufacturing.

Brutal and sophisticated, this twin-turbo V8 remains, from the factory, short of what its performance promises. With the valves open, the Rog cat-back gives it a technical, furious growl, the breathing of the turbos and sharp bangs on the overrun, all the way to the top of the rev counter; with the valves closed, the LT becomes more civil for the drive to the circuit.

Under the “Manifold” option, the LT can receive a catalysed downpipe, the part that follows the V8’s turbos. An ECU remap is needed to turn it into horsepower, and our page then lists 905 hp and 950 Nm at Stage 2; fitted on its own, it acts on voice and weight, and its 200-cell variant keeps emissions control.

On such a precious car, nothing is welded: band clamps, gaskets and about two hours of workshop time are enough. Factory valves retained, or the Rog remote. On a car where every gram has been hunted down, titanium is almost a must: around 40% lighter than 304 stainless steel for the same design, in brushed, gold or purple.
