I don't have an exhaust on my car but I have heard a few. Seems that all slip-on/rear section exhaust that retain the OEM cats don't really do much to the quality of sound...they are all fairly quiet - a diffence of a couple +/-dBs. So I think any exhaust you choose will be pretty similar just depends on how loud you want it. Also, take into account that even a straight pipe or ACM isnt that loud. In fact the ACM/straight pipe is almost the exact same thing as the BMW performance exhaust, which is a striaght perforated pipe enclosed with now insulation. I really dont think you can lose with a Megan exhaust, expecially for the money.
