The ground basis is done. It doesn't completely sound like in the referencevideo. The blow off valve is different. So is the low ontouring. But, it's not the final, and not the only version that will be there. The referencevideo is there to show how high this car can sound, I think it is at least an 800 hp car. Could be 1000.
