Hi, just bought my 2016 435 last month. I have watched lots of YouTube videos and it seems people get the burbles sick then they sound better with the MPE. Right now I do not get them at all in sport more or sport plus. Is that ok?
Thanks

I'm completely stock and gets lots of burbles on 335 with the MPE. Im actually probably selling it soon so if you're interested DM me.

give it a few hundred miles to break in the MPE, mine took some time but now burbles a lot more. I find that it burbles more heavily in eco mode ironically lol

I've noticed that too which is weird to me because you would think that overrun would negatively affect fuel economy. :

I wonder if my tune has anything to do with it.

probably does not have to do with the tune, mine is tuned as well and it took a few hundred miles to really break in. In my experience, with new catbacks/axlebacks this is a very common thing.

Give it some time and you'll be good! I'm considering selling my JB4 and picking up BM3 tune so that I can customize my burbles lol.

I've had my exhaust for over 2 years and my tune for over a year and a half. I think it's pretty much broken in by now.

oh my bad lol i thought you were the OP, and didn't look at your response correctly. I think you were referring to it burbling more in eco mode? im not sure if it has to do with the tune, because i've read that this seems pretty common.

Pretty interesting!
