I have it installed on my car. I find it to be the perfect for what I was looking for. It isn't overly aggressive, which fits the personality of the non-M 5-series. In Sport Mode it is audible from inside the cabin, but not overbearing. I have mine mated with a BMS Intake and am very happy with it. I will say that it is pricey so you may want to look at other options as well, but I purchased mine used, so I saved significantly on the price. I am located in Nassau County, Long Island, about 15 mins east of JFK airport if you ever want to link up to hear it in person. Hope that helps.
