Yes I am. They all sound bad. Their factory exhausts mask it as much as possible- but it's there. Don't forget about all of the Dodge Vipers as well.
A Lamborghini Huracan pulled into the gas station and into the pump right behind me 1 week ago. One of the re-skinned Audi R8s with the "Lambo" V10. He had an aftermarket exhaust so you could hear it coming a block away and he couldn't drive for shit, so he had to do two 3-point turns to get around some Nissan. We got a good long does of it's various exhaust tones.
it sounded bad. When I got int he car to leave, my wife commented and said how bad it sounded. Not because it was loud either, we have some loud vehicles she likes the sound of. They are all V8s.
