A new supercar video from the streets of London is here to show us an extremely loud Mercedes-Benz C63 AMG Black Series, fitted with iPE (Innotech Performance Exhaust) exhaust system and sport headers. Actually, the car is so noisy it frightens two girls walking past.

Meanwhile, a black BMW 6-Series Convertible also passes by revving hard causing one of the girls start screaming. It seems that being a supercar spotter in London these days is quite an entertaining job.
