Need the forum’s help! I have a few days left to add/change options on my build and I’m am undecided on the exhaust. This will be my daily - when I test drove the comp I noticed a fairly significant low frequency drone at highway speed that I did not recall being present in the base I drove (base had standard exhaust). I am now wondering if I had the settings off or not. Does anyone having the m sport exhaust in a non-comp (base) notice a drone at highway speed (low rpm / overdrive) when they have the button off and engine in Normal setting? Also, am I correct in assuming that ASD “fake exhaust” sounds are turned OFF when in settings of engine normal / exhaust button off? Thanks a bunch!

Get port installed M performance exhaust, not M sport. Sounds great, looks great, no drone.

What is the difference between the standard F90 exhaust, the M Sport exhaust and the M Performance exhaust?

I believe the M sport exhaust is the optional exhaust upgrade ($1500 on Canadian builds) which just has less perforations in the x-over/resonators (bit more aggressive sound) and comes with black tips. The M performance is a more costly affair with some titanium (no doubt more aggressive sound) and is a port installed option I believe.

So, CanadianF90M5, any drone when you have yours on normal engine setting with exhaust button "off"?

I have this exhaust NO drone.

hey Canadian F90M5 I saw you responded to my question in your "two week" thread where I first asked it. Thanks a bunch! Let me know if you notice any drone now that I have introduced the concept via subliminal suggestion lol.

I agree that the M5 Comp with standard Sport exhaust has no drone on highway or otherwise. No need to even cut off the console switch.

[CanadianF90M5]

I can test it tonight, in both modes (on and off) as I continue my nightly drives to get my Km's to 2000 👍🏼

Do you recall at what speed?

Absolutely no drone in my comp package! I love it!

Just confirmed ... highway driving with curse set at 125km, economy, sport and sport plus, with exhaust button on and off ... no drone

Appreciate the test report. Thanks a bunch. Hard to say why / what I was hearing during my comp test drive as the exhausts should be the same.

I’m still confused. I ordered (built via the BMWNA website) on 5/18/19 [production completed on 5/28 - awaiting shipping now...] and there were and still isn’t any option to choose an exhaust system option. So, my question is: What is the default, factory installed, exhaust system that I am to receive?

If you ordered a standard M5 you get the standard exhaust.

If you ordered a Competition M5 you get the sport exhaust.

If you did not talk to your dealer and add the M performance exhaust, you of course will not get that with either car.

The only exhaust you would pay extra for on top of the price of either car is the M performance exhaust. And if you're not sure, I guarantee you did not buy it.

[bradleyjs]

I ordered the M5 Base so it’s going to be Standard exhaust. Is the Standard good? I personally don’t want to have the loud, raspy and guttural exhaust sounds anyway. I’m prefer it to be conservative in nature. So, my guess is, I’m probably getting what I want anyway w/out shelling out more cash.

Thanks for your quick reply!

My F90 Comp with the M Sport Exhuast has no drone.

But I would like to check with owners with the M Sport Exhuast. Does the Exhuast button on the centre console do anything? I tried pressing it on and off but the volume and sound of the exhuast seems to be exactly the same. Anyone else with the M Sport exhuast has a different experience?

[Demon Barber]

With the M performance exhaust, which is totally valveless, the button will control crackles/pops on deceleration/downshifting. I assume it would be similar with the M sport, although it has valves unlike the MPE.
