Unofficial info is that this was done via ECU not mechanically

Just describing my perception.

I wouldn't void my warranty to get these back but think the exhaust could be a bit more beefy. My only options are a axle back unit like Akrapovic / Remus etc and no sounds clips out there for axle back 2020 models! Cheers..

Some of the owners have had these fitted and got a CEL, then when taken into the dealership, they have been told to remove it before they will look at it, be warned.That's in the UK.

Ok cheers John. I thought that was the full system (I.e. cat back) not just the back box? If that's the case then very annoying as its means I can't make any changes to the exhaust!

Correct slip on = axle back. I will post some clips once I have it installed. I think it was supposed to ship tomorrow, 1 or 2 weeks delivery time, so it will take some time.

Unlikely that you get a CEL from just the axle back. You'd definitely get a CEL if you install the X pipe on an OPF car, Akrapovic even say so on their website.

And this is the car with ID7 as are all cars AFTER 1.7.2019

And yes BOTH are competition both were in SPORT PLUS and filmed with the same camera. Waiting for BMW to see how we can resolve the issue as none of the BMW dealers had a clue that BMW changed the sound with ID7

You're saying all cars with iDrive 7 but you mean just in most of Europe, right?

That's how it is, ID7 new sound only EU and Switzerland are affected.

[Slayerkillhate]

Any solution to make it sound like car with ID6 on video?

Well that is THE question......Currently nobody knows what exactly they changed

Whats even more interesting/annoying, is that ive heard that UK cars, even fitted with OPFs, and have had some pops and bangs, have gone in for service, and come out even quieter than when they went in. I dont know if this is 100% true, but if BMW are downloading a new map so to speak to meet new noise/emission regs etc, how annoying is that ?, and is it even legal ?, taking away what most folks deem to be their favourite part of the experience ?. All getting a bit murky indeed, you cant seem to have anything these days, all a bit sad really ???

More likely the opposite.. Take a look at the m5 update thread.


„Ok,i just did software update.
Car is different,exhaust sound is fruittier,and volume is deeper."

Not looking good for the new M3/4 with this new legislation, all cars are getting this, makes me think this could be my last "M".

I just got my 2020 non comp back after running in service. The sound is exactly the same, no difference for me. Still no sign of a crack or pop unfortunately.

In the minority it seems though.

I'm with ya.. I prefer a deep/throaty header sound if anything

Having said that. My 2020 doesn't pop.. it does burble some though but not enough to really bother me. But then again I haven't put exhaust and DP's on it yet

I must admit.. I'm also not really fussed by the pops and bangs. I'm with you on the deep/throaty sound. That's all I really want... Unfortunately for me (and us EU guys) we're f*(ked. We can't even change the exhaust without the dash lighting up like a Xmas tree!

Thanks John.. very depressing... I'm tempted to see if you can open up the rear box and replace the pipes with solid ones like I did on my M3..!

[Nikolov]

I had my Akrapovic axle back installed yesterday. No CEL or any error lights so far and to be honest I'm not expecting to have any. The only reason why you'd get a CEL from an axle back is if you don't connect the valve lines.

Initial impressions are the exhaust has a throatier sound at low rpm and the pops are a bit more pronounced (my car already had the burble and pops). Sound will probably improve after a few hundred miles on it. I'll try to get a proper external GoPro mic with a windguard, before I make a video.

.

if you mean the flaps then that is not true,mine were disconnected at delivery by BMW on my request and never caused a CEL. it has some kind of errors(flaps malfunction/disconnected) that can be seen when plugged in by dealer but never CEL.
i did have CEL and limp mode cause i removed the OPF and then had to reinstall them to get rid of it .almost 7k+ miles with only the flaps disconnected now and no CEL so far
