My friend installed the factory race exhaust on his 2015 LP 610, the 0-100 km/h remains the same, but 0-200 km/h is 0.4 seconds quicker than before, also quicker lap time in track, the advantage is obvious on track, the sound is not as loud as other aftermarket exhaust. The factory race exhaust package can be installed by the dealer, the information provided by the factory are written in black and white: 5% increase in horsepower. By the way, Ontario is a beautiful place, especially Toronto.
