I never said it does. But what I did mean is that it doesn't need to. Again, with Amuse's expertise I'm sure the car drives amazingly well. Yes, the exhaust/body combo creates a little drag, but so what? The car's made to showcase a product, you said it.
But he's wrong about "proper engineering." The exhaust shaves weight, and creates more power while looking absolutely gorgeous on a street car. I call that proper engineering bud.
For those doubting their engineering, watch them go toe-to-toe with some of japan's best tuners. And completely destroy them.
I think our definitions differ somewhat. have you ever tried running with a parachute on your back? Even the best designed, lightest parachute is going to slow you down.
