Heard this muffler in person today. Not bad without downpipes. Not great either. I don't understand why BMW chose to keep the 2 cylinder sets separate rather then bringing them together with an X-pipe or balance tube. It would sound so much better and probably make more power too.
I'm thinking about getting it, but I really wanted to keep the valves in the exhaust. I drive around my senior citizen parents in this truck, and having a loud exhaust isn't a good thing (well, it is to me, but not them).
