Exhaust of V10 Track Engine from BMW M5 Glows Purple [Video]
Besides sounding like an F1 car now, which it probably could have been, the engineers at Dinan have fitted with an exhaust that turns purple with the scorching heat when it’s revved.
The V10 has also been given new bore and stroke, which has resulted in a displacement of 5.8 liters. But after hearing of the racing dry-sump oil system and the performance camshafts, all we can think about is that exhaust. We could be wrong and this might just be the camera playing jokes on us, but it’s still worth seeing purple headers.
