It was crazy to see not one but two straight-piped Porsche Carrera GTs in London in just two days. The first features a GMG de-catted exhaust whilst the second is equipped with AWE straight pipes, both sounding insane. The black car can be seen powersliding through the city and losing traction throughout. This masterpiece by Porsche features a uniquely-developed 5.7-litre V10 engine with 604 brake horsepower and is widely renowned as one of the most difficult cars to drive. Many are kept away in garages and hidden from the eye of the public so it was fantastic to see both of these out and about.
