Truthfully Shawn, the car isn't much louder. You do get a little more pop/crack out of it when down shifting. I would try to talk the wife into getting a sound clip with her camra, but I know she won't do it while the car is in the garage. She will absolutely not even be in a garage with a car running, not even for a minute. I can't move it outside at the moment, it's kind of taken apart.
