Not sure if the cut off valve leaks a bit because when the valve is closed the start up is now much louder but not really in a good way
I am now thinking of replacing with MPE or Remus axel back, hoping the sound will be a bit more refined, less obnoxious and fart canny. I like the deep gurgle sound on the M2 at low speeds.
How is the drone on MPE and Remus

I can only speak for the MPE, but for me it's perfect. Louder when you want it, quiet when you don't. Even with the valves fully open in sport mode, around town it is present, but not droney at all. I'm very sensitive to drone, too. Few things annoy me more than anything obnoxious exhaust.
