TUNED McLaren 720S Stage 1 800HP Destroys Porsches on Track!! - OnBoard with Incredible Sound!

In this video I take you inside a friend's tuned McLaren 720S for a few hot laps around Monza circuit. This 720S is fitted with a Stage 1 ecu remap by Monza Garage and a custom exhaust system. Thanks to these mods, the car now puts out 800 horsepower!
