1980 Porsche 935 K3 Turbo by Kremer Racing

[19Bozzy92]

This is probabily one of the best racing Porsche I've ever seen. Always fantastic to hear the whistle of the two turbos while they are working and the gorgeous flames from the exhaust.

I saw it has two different exhaust systems. At the first time I thought they worked like the Ferrari F40 exhaust pipes but I saw the flames came both from the central exhausts (when the car was downshifting) and both from the 2 little ones (when the car was changing gear during the acceleration). Why this? (you can see clearly the back of the car at 1:26 in the video )
