The exhaust law has slightly changed in CA recently and people with aftermarket exhausts are getting ticketed left and right at certain locations. After seeing an OG M2 owner got ticketed with just a port installed MPE, I decided not to risk it. So this was one reason... I also heard Remus Race paired with stock midpipe. It sounds pretty decent but not sure if I love the tone. Remus Race muffler is also kind of a joke IMO. This is not necessarily a bad thing for many people but let me explain. When the valves open it acts pretty much like a muffler bypass but in my case it was still pretty loud even when valves were closed because the "muffler" has minimal or no restrictions internally. Therefore, I hadn't noticed such a big difference in volume between valves open and closed.

If I were to do this all over again, I would go for the Remus Sport (instead of Race) paired with AA midpipe. Who knows, maybe it'll be the next move for me but due to the recent exhaust law changes, I'm leaning towards an OEM option such as MPE even though I might still get ticketed even with an overpriced MPE (but at least it'd be easier to fight against).

Get the Remus Sport! I believe the sport will be much quieter with the valves closed.

I don't think it's out yet

Well the part numbers were posted earlier in this thread - I think that info came from a dealer's site...perhaps they're listed, but not yet available?

[hellrotm]

They must not be available quite yet.

[desertking]

Got a confirmation from dealer, that the M performance exhaust system part number can be seen now but actual release in October.

[VIERsr]

A lot of money, a long wait, is it really worth it whereas we don't even know how it sounds?? There are a lot of options on the market

At least one dealer/parts specialist over here in Germany got them in Stock and took me a photo.

Sadly my dealer told me the exhaust isn't certified by german law and BMW says it's not suited for OPF cars. So putting it on may void warranty and get me a ticket. Otherwise i would be the first one to get this exhaust.

Bullshit, it is not "suited" for OPF cars. It works 100%! Germans won't get TÜV certification papers for it and therefore it is illegal, but anyone else in Europe or the rest of the world can buy one and install it on his car.

Thanks for sharing! I really don't understand why BMW allow EU based dealers to have these in stock while most of the NA dealers are still waiting for inventory. If it's not approved for OPF cars from a legal perspective, what's the point of having this part in stock? I feel like BMW should have given the priority to the NA dealers.

EU and US are different versions.

There is no EU version. There won't be an MPE for OPF cars and that decision was made last year due to the emission law changes in EU. So the MPE shown above is for US spec cars as mentionee by the post owner.

if the exhaust will only be the muffler how is that not going to be compatible with opfs?

Legislation and the chances are that this slip-on exhaust like other non-homologated systems (e.g. Remus Race, Lightweight, etc) will throw OPF error messages on the dashboard stating the flow is not within limits.

The OPF sensor will measure a faster flow due to the decreased back pressure of the better and more free flowing slip-on/backbox/rear damper, and will therefore throw engine warning lights and error messages at you when you are driving the car at a decent pace.

So far only the AC Schnitzer, Remus (Normal) and Akrapovic slip-ons don't seem to have this issue! All these are EU-type homologated.

Was it discontinued or is a ROW-EU version?

There is only a US version, there is NOT a EU version, but you can fit a US version on an EU car if you prefer.

BMW originally announced two versions of MPE, one for US spec cars and one for OPF equipped cars. However, shortly after that announcement (about couple months later), BMW made another announcement saying that there won't be any MPE for OPF equipped cars. From a technical point of view, you can fit US spec MPE to an OPF equipped M2C (as mentioned above) but it probably won't pass emissions in EU.

That really sucks for the EU customers but the US spec vehicles have been getting shafted in comparison to EU spec vehicles, within the last couple of generations, in power and equipment, so I guess the tables has turned.

I doubt we'll ever see a OPF make it to US vehicles since the EPA already determined that it's only really necessary for diesels.

Dodged that bullet..

Finally a hint at a real unit. Hopefully we'll finally get one and get to hear it! Anyone order one thru a dealer yet?

Sooooo...I just picked up my M2 Competition and all I have to say is WTF is everyone complaining about?

When I first pushed the start button the car emitted one of the loudest, deepest evil growls that I have heard in a long time.

I really listened to my N55 M2 prior to trading it and my perspective is that most of the sound we hear is from under the hood, engine, intake and whatever else. Not saying the exhaust isn't awesome and doesn't burble like a silly school girl b/c it does and sounds fantastic in its own right, adding to the total aural symphony.

That said...and mind you the M2C only had 16 miles when I first started it and has a loooong way to go before it's broken in but the engine has a deep growl and the exhaust is also fantastic. Together they also sound awesome, just a different awesome and actually one that I like a bit more. If you don't hear the burbles, play with engine button (sport plus), lower the windows and turn down the radio. The burbles at least right now are less in my face and have a nice deep low sound.

So all said IMHO the S55 and exhaust are sound fantastic and different than the N55. In fact, at some points while driving home I would hear the faint undertones of the N55 from engine letting me know where the S55 came from.

Sounds like you enjoy the cold start and the ASD. Once the car warms up, the car gets quiet. With ASD off, the car is pretty much dead quiet and you have to roll the windows down to get some noise. You don't realize how much fake noise if being pumped into the cabin until you have ASD off. Also I would say the M2C burbles more and higher pitched compared to the deeper burbles on OG after driving both back to back.

I was standing outside the car when I started it. So probably not the ASD, at least for the cold start.

Though on the drive home the M2C had something going on that gave me a bit of a headache and 1/2 the ride home was with the windows down. If it's from the ASD, I'll remedy that tonight with the Technic PNP and let you know.

Might have just been the essentially toxic "new car smell". I've always had issues with minor headaches until it wears off.
