Get a Billy Boat exhaust and you can be loud without being accused of being a ricer.
I am only half joking. The BB exhausts are known for being mellow until you floor it and wind the engine out. I had one on my E34 Touring for a while and it was fun in the right setting. Unfortunately, it did drone at highway speeds and I have duties to schlep my kids around so the BB had to go. Before I removed it, there was one beautiful summer day when a woman on her cell phone was holding up a long line of traffic on a country road near my home. She was doing 30-35 in a 50 mph zone for about 10 miles without paying attention to the traffic building up behind her. The startled look on her face when I legally passed her at full throttle was worth every penny. I could see your idea about an exhaust cut-out serving the same purpose.
