[Insane Exhaust Video] 2018 BMW 440i xDrive M Performance

In this video, TheStraightPipes takes a detailed look at the 2018 BMW 440i xDrive M Performance model. In its stock form, the BMW 440i Coupe is powered by the B58 3.0 Liter straight-six BMW TwinPower Turbo engine with 320 horsepower, 332lb-ft (450Nm) of torque, 0-100 km/h (62 mph) in just 5.1 and electronically limited top speed of 155mph (250km/h). Add an M Performance Power kit and it becomes unstoppable at 355 horsepower and 369 lb-ft (500 Nm) of torque. The best part of this upgrade is the insane M Performance exhaust system. Perfectly matched to the 7,000 rpm straight-six symphony and creamy smooth 8-speed ZF transmission, the BMW 440i xDrive sings one of the best tunes in the automotive world and gets us just a step below the much famed BMW M4 models.
