Both of these youtubes seem to sound better than the Akrapovic.

Damn I know. The cost though wow. Also I don't necessarily want anything over the top loud as can be but this being OEM is very appealing to me.

MPE sounds great, but it's pretty sad that I have to pay BMW $6k so the car can sound and look like it should have when it left the factory

Curious, anybody looked into armytrix at all?

Stainless, with a number of tip options and remote valve control (love the term “beast mode”)

The MPE I had on the F80 sounded excellent and looked the business (attaching some pics). If it's titanium for the CS and available in Aus I may well go that way. I like the idea of having as much of the car original BMW if possible. I should confirm Australian availability by Wednesday I'm hoping. My parts guy is off today on a long weekend but is onto it Wednesday first thing.

That said, going Remus or Akra can also work, particularly if you're going to part out at the end. The CS however is the first car I've bought which I am thinking I may not sell. Who'd have thunk it.

Your M3 Comp was grey yeh?

I like how it sounds. Open your window. It's going to be really really nice in a few thousand more km.

Here's a quick iphone video of the MPE on my M2C... not the best quality but it gives you the idea... much deeper and louder sound than stock exhaust.

Quite restrained in Comfort, but if you're neighbors are close, they will hear the cold start EVERY time. It's a running joke in my neighborhood!

True, should have been included on the CS (like it was for the GTS). You would pay about 5.5k if your dealer adds it at cost, and likely closer to 4.7 if you buy it afterwards (could also sell the OEM and recoup a little bit of the cost)

Mineral grey here too!!!

And yes, the exhaust construction is titanium, same as the M3 version. Only thing different I see so far is the construction of the CF tips (the attachment screws and length of the CF part are different).

Left is a stock image and right is with the MPE


Also forgot I had this from transport. All pretty much at idle, so not super interesting.

The exhaust on the left car looks so crooked... I had the same issue with my M4. Fixed it by getting an AWE exhaust. I don't know wtf is up with BMW quality control, but c'mon thats bad. I won't even mention the shitty paint job they put on my car.

I've seen/hallucinated that crookedness on a few comps but no clue how it could be because the U clamps are not adjustable.
Maybe just an illusion

I'm pretty certain it is not unfortunately. My M4 muffler hung the same way with the driver side lower than the passenger side. My guess is poorly positioned exhaust hangers welded on muffler itself although I think maybe my AWE exhaust might have been slightly off kilter as well. It just wasn't as noticeable since the muffler itself was narrower, and the tips were adjustable (and I really didn't want to know).

The reason is crash safety of the rear end of the car. The main reason it is hanging so low is that when you have a rear impact from someone else driving into the back of you, the exhaust slides downwards and not upwards plus inwards.
This was the official reason to hang the rear muffler so low, while we all know there is a lot of space above the rear muffler. They could have put it higher into the bodywork, but crash safety stopped them from doing it.
Clear answer if I say so myself...

Everything you suggests cost additional money and effort, while they have to cut cost levels and not make the car more expensive.
Painting mufflers is not something I have seen a car marker do. I wonder how reliable that is on the long run.
M Performance still hangs quite low in comparison to other systems and is only homologated in the US. Doesn't cover the whole world, a stock exhaust should...

4. The exhaust on the CS has two changes from the M2C. It has a new mid damper and larger CS style tailipes for an enhanced sound volume. I heard the car and the sound is not that different from the M2C. It is a notch louder.

Something to consider if swapping the exhaust. 1. How is my safety impacted? 2. Could this result in a total loss vs a repairable accident in the event of a rear-end collision? My thought is that #2 could be the more prominent and real issue. Something to consider when you can't get another one.

Well, if it were a fuel tank and the cars gets rear-ended:

[MinionM3]

With MPE are you having to cut the stock system or is it a full replacement?

Do these questions matter even for MPE? I'd hope BMW crash tested, or at least designed the MPE to act the same way as the stock exhaust.

Cut after the sec cats.
Also fully emissions compliant

It doesn't matter for the MPE because it hangs low as well, similar to the stock exhaust. Just looks different.

You have to cut it.
