Exhaust Flap - What RMP do they open? M60i
I've gone the tried and true fuse pull method with many BMWs (M550 being the last). The M60i has flaps on both sides, as confirmed by a $25 screen endoscope purchased off of Amazon.
At what RPM level do BOTH flaps open? On previous BMWs, it was put in sport plus after oil temps were warm, beat on it and pull the fuse. I have searched the forum on this topic. Lots of people who have gone the controller route for the flaps. I don't see that as necessary as I have had zero issues in almost 8 years on multiple BMWs with pulling the fuse. |

I don't think you can have M60i exhaust flap fully open while the car is standstill.
BMW really did an excellent job making exhaust on this car as quiet as possible... |

On past models, if you warmed the car up before driving spiritedly in sport/sport + mode the flap would stay open when stopped (long enough to be able to pull the fuse). Sounds like I'll have to wait and find out once the car is broken in

You might be able to use Bimmerlink to manually open exhaust valve one time. Last edited by parky1215; 04-24-2024 at 08:21 PM.. |

They open little bit more when you actually drive in sport/sport+ mode and it probably only opens 100% when you reach full throttle in high rpm range. Exhaust valve flap would go back to closed position as you slow down. |

The answer you don’t want but are looking for is it opens only when driving, in sport mode and at a certain RPM ( I have heard people say 3,000rpm but I havnt confirmed).
Only way to open exhaust valve is to remove the motor controller on the valve, and manually open the valve then secure it so it doesn’t close. When doing the same research and realized this was the answer, I gave up as the sound difference wasn’t worth the hack job. |

I recently connected Bimmerlink with OBD ENET cable to clear some codes. Unfortunately, Bimmerlink app does not give option to open exhaust valve via app on M60i models.

Had a chat with a friend yesterday. I pulled up in my M60i alongside his Audi SQ7. It was a horrible experience to suffer all the laughs I had to endure when I started up my engine and compared the notes with his… we are talking equivalent models here, right? It’s not like I was going against an RSQ7 which would be the Audi’s version of the proper X5M…
Audi sounds great. The AMG-light version of GLE (53) sounds great even with a six-banger. Hell, even a diesel X5 with its own version of “sports exhaust” sounds better than the M60i (which is a freaking awesome 4.4l V8) Why?

From what I can find, no one knows for certain when the flaps ARE FULLY open. Once I'm past the engine break in period I'm going to use the endoscope camera I have and try to confirm when the flaps open. Last edited by IL X5 M60i; 04-30-2024 at 10:20 AM.. |
