The " issue " about the M2 Competition sound is that each turbocharger is connected to 3 cilinders (not 6) , and as you explained, each one has an indeendent exhaust pipes, so from the driving seat it sounds more like a 3 cylinders then a 6 ! The two sounds are "meeting and mixing " just at the end in the rear mufler. This is the reason it sound so "strange" compare to the M2 LCI " So it is damn different, then based on personal preferences it can be nice or not !
If every other sound pulse has to travel further before it meets the other sound pulses they don’t come out with the same time between each pulse. Eg 1-5-3-6-2-4 note the time between pulses 5-3 and 6-2 are longer than the time between 1-5 , 3-6 and 2-4. They don’t cancel each other out, they are individual explosion pulses. If you listen to it slowed right down you can hear each combustion cycle. Each sound pulse travels at the same speed, if every other pulse has to travel a longer distance the timing is out. They would cancel out if the exhaust was twice as long on one side it would sound like a 3cyl engine. But it’s not even close to double the length it’s more like 10% longer one side.
So finaly you installed the miltek, does that mean that you removed the OPF filter? therefore Co2 goes up right? in france every 2 years we have the technical control mandatory, they do check the pollution, do you think that pollution will increase with miltek? otherwise it means that before the control i would hve to reinstall the old exhaust pipe which i dont want. Thanks.
I've installed it last year, so quite a while back. Like I've said in the video (you didn't watch it, did you?) 😁, the exhaust doesn't remove the OPF but it does remove the rear silencer. As for the rest, you are correct. You won't pass an inspection with this milltek system
@@TunedIntoCars I saw the videos, but in the first one you said that you won't install anything because it is illegal in the EU, and then second video you show us the miltek installed... hence my confusion, perhaps you found a "legal" system between both videos... anyway thanks for the explanations. Basically there is no legal system, except perhaps the overpriced M performance exhaust.
There's no M performance exhaust option for the competition, at least in Europe. But there are plenty of fully legal systems. Even milltek has one. Basically most systems that only replace the backbox of the car, is legal. Just make sure it's EC approved before you buy
The very very short version of it all is that you are basically hearing two 3-cilinder engines. Such a pity and the reason why I will always avoid the S55. and stick with my S65😊. Or spend some serious miney and go for a single turbo configuration.
@@TunedIntoCars hmmmm don’t think so.. it is somewhat better (less annoying) but still a bit of the same in my opinion... click here and see what I mean😁 ruclips.net/video/vfvJRW_tkEc/видео.html
For those in Europe who have to deal with OPF deleting issue regarding limb mode, THE ONLY SOLUTION : OPF Deleter by LEIB Engineering. It will allow you to install the Active Autowerke midpipe easily. Enjoy !
I just bought an M2C 3 days ago almost same specs as yours, thanks for your very interesting videos. Seems that the only legal option here in Europe is to replace the muffler by some aftermarkets brands like Remus, or Akra and that is costing a leg..
@@TunedIntoCars After some digging i found two to other brands that seems to comply with the regulations, Bastuck and Eisenmann, the bastuck muffler is "only" at 2500 euros, could be an option as well..
@@guillaumeduval1166 I've actually ordered the eisenmann a couple of weeks ago. So hopefully in February I'll have a video up detailing everything about it
*edit: I commented before listening to the whole video and didn't listen when he discussed the downpipes/turbo setup. ** From what I have seen being discussed alot is the uneven length downpipes. It apparently causes uneven exhaust pulses, taking away from the well known 'Inline six' sound. Installation of even-length mid pipes currently seems to be the biggest solution for this aspect of the issue. However this sadly may not be an option for the EU configurations (I am not entirely sure).
@@TunedIntoCars You got me haha. I had the video running in the background while I do my daily housework. I 'jumped the gun' to comment on your video. I likely didn't hear the latter half of your video. You mention exactly what I said in your video. Apologies! I shouldn't comment without listening.
Can this "engine noise" debate be appropriately described as being EU and UK issue only? As you indirectly note, export models sound much better thanks to no particulate filters despite the twin-turbo setup.
No, not really. I didn't say or suggest that export models sound better. They sound the same but they are louder I only said you can fit an active autowerke equal length midpipe that does solve the sound problem.
It’s not an EU/UK problem. All M2 Competition and CS models have this issue. The US doesn’t suffer from the GLF/OPF requirement, but there is still a 14” difference in pipe length from one bank to the other. The only way to solve it is to equalize the length between to two pipes. I have a US spec 2020 M2C and have the same issue.
@@C3Motorsport you talk cluelessly, because the CS has an altered exhaust to start with. As Paul notes, and you not being the only M2 owner, export cars are indeed louder, and I add better sounding than EU and UK ones. Some of the USDM options make it sound tinnier and cheaper to the point the OEM exhaust isn't bad at all especially after the pipe "cure" overtime. What happens up top, due to the twin turbo setup is relevant of course, but not the whole story and with less effect on cars without OPFs. If you really must have a louder and raspier M2C, an MPE is the best option there is to my ears (which is what CS almost adopts). Everything else is wasted energy. You go around claiming otherwise from Germany and holding on the fact that your ex N55 sounded better... when it's essentially a different engine. This background explains your comment fully :) (and have you physically checked if you have OPFs anyway?)
@@nessuno5403 not clueless at all. I’ve been under my car several times as well as several others (EU spec, and CS). The pipes are all physically different lengths. I don’t understand why you seem to have trouble accepting that. The particulate filters muffle the sound, they don’t change the tone. Its still raspy with or without it. And while the back box on the CS is different, the pipes leading up to it have the same length problem.and yes, the N55 didn’t suffer from the issue because it was a single turbo, so there is no unequal pipe to cause the raspy sound.
@@C3Motorsport so do you have a photo of your German-delivered exhaust system? That'd be interesting because I bet the answer will be you haven't experienced the non EU/UK version - equal length pipes or not :)
The cost of the new exhaust and minimal sound improvement does not justify the replacement. I have not been impressed with any of the top brands exhaust sounds. Leaving it stock however I do live in United States.
But have you listened to them in real life? You won't get a good idea of how loud an exhaust is on RUclips. Microphones can't really capture the sound properly. I think, even in the EU, replacing the backbox makes quite a difference. In volume at least. Acoustics is subjective, of course.
@@TunedIntoCars I only heard a few in person and the few I heard would be very embarrassing to have on my M2C. I do agree with you that the utube platform does not do the exhaust sounds justice. Keep up the good work. I enjoy your videos
@@TunedIntoCars very true... whenever it goes up on a ramp i’d be so embarrassed though😂 it looks like you’ve let the apprentice weld you an exhaust with the spare bends😂 plus i’m sure the flow of the midpipe will be horrendous!

Thanks for watching, everyone!
Absolutely right, it’s plumbed as 2, 1.5 litre 3 cylinder engines.
I got Akrapovic DPs and AA midpipes and the car sounds amazing!!!
I am pretty sure that there is a resonator instead of another catalytic converter behind the OPFs in the EU Version.
The secondary cars and PPFs are all in one unit. There is a resonator behind that, and the rear box muffler behind the resonator
Man I am really torn between hockenheim silver and black color. But man this car looks a lot killer and unique in black especially the rear!
Black just got the edge a little in my opinion

I really like the sound!
finally the one regarding m2c thx
I think the N55 engine on M2 Lci is still the best

Nobody said it's double the length. I just said it's a 40cm difference, which it is
