So far, so good. It was only a 5 mile drive home and I had the top up, but the exhaust tone is notably quieter...not quiet, but quieter! I like it. I didn't get over 45, and didn't really have a place to really get on it yet. Walking around the car, the tone is definitely more tame, not near as throaty, but still aggressive.
