In order to make these files small and quick to download, I recorded them in 8-bit mono format, so the sound quality is decent but not great. The recordings were made with the built-in microphone of a laptop computer sitting on the ground off to the side, about 3 feet from the back of the car.
Remember, I also have a Rebel Motorsports Ram Air Intake, so that affects the sound as well.
