Tried the exhaust valve mod, now what
I wired the exhaust flaps open on my 15 competition expecting a little more sound.
I was wrong. The cold start was epic loud, like shaking building loud, and lower rpms was much louder then before, actually not a moderat difference, but a lot louder. Soo much that there is a big drone problem now, almost sounds like there is a subwoffer back there radiating low frq bass notes, and its like pressure in the ears. Other problem is that its only the low rpm`s that benefit this mod, above 3000rpm its the same as before. Now the good stuff, static reving not finally sounds prober menacing, like somekind of pluck have been removed, and the overall feel of the car now is more like driving something special. The mod must go because of the drone problem, but what are my choices if i want more sound but no drone, and a tad more agrresivnes in the higher rmps, without spending stupid money on a akrapovic system ? |

^^If he doesn’t like the flap mod because of drone, he will hate the Soul. I’ve had both and the nonexistent (IMO) flap mod drone is nothing compared to the Soul setup.

Did you also disable the fake exhaust noise? Maybe the fake noise from the speakers is the droning noise?
While it is a bit of a pain to connect up and open an app to make the flaps open, I use bimmerlink to open the flaps and turn off the fake noise when I want pure good exhaust on my 15 comp then leave it normal (don't start up the app) on days I don't. |

I went with ExhaustMeister. If you search the threads you can read some reviews. When I bought my M5 it was straight piped which sounded cool, but very loud on cold start and did not want to wake the family every time I left the house early.
I bought the standard comp pack exhaust and then added exhaustmeister. I can switch the valves to open when I want that extra sound but then keep it tame when I don't feel like it. Exhaustmeister was easy to install and I added the buttons to two of my garage door openers to actuate the valves on and off. As a side note, when the car was straight piped the drone was terrible on the highway. |

Thanks for all re replays, I looked at the exaustmeister, but the page does no long excist:
I found a store on ebay that sells them, but the link from ebay store to the exaustmeister does not work. I dont like spending money in something that has zero afterservice. The soul exaust seem like the right choice, also because it saves alot of weight. Only problem is that what i really want is the akropovic cat back system, but there is no way of justifing the money it costs Last edited by The Dane; 11-22-2020 at 01:02 PM.. Reason: dobbel post |

If you have a local muffler shop willing to do the work you could weld the first chamber shut on the muffler and purchase the electronics to open/close the valves. It is basically a stock muffler with them closed and a muffler delete without drone with them open.
