D3 considers themselves as “the premier manufacturer of Cadillac Tuning Equipment for both street and track.” Their efforts have even led to a technology co-op with General Motors, so they know what they’re doing with “The Standard of the World.”
But, like GM Authority mentioned in a recent Corvette article, General Motors is building some world-class vehicles but, like everything else, it can be improved. The current object of their affection is the CTS Vsport. With a twin-turbo six and 420 horsepower, it has no trouble getting out of its own way, but D3 Cadillac’s customers have asked for something with a little more tone to it. That being the case, D3 is developing a new exhaust that addresses that while delivering improved performance.
This exhaust system is “coming soon,” but you can still check out the clip here.
