Center Quad Exhaust

New to this forum and will have an M2 allocation in a few weeks..
I have read numerous comments about the center quad exhaust being way over priced.. but I don't see any reference to who makes the exhaust for BMW or sound clips.. I believe I did see that it's a titanium muffler can...Does anyone have info to help understand what we get for $8k ?? beside being laughed at by the community ....

Not sure if it's made by a company other than BMW (it might not, like the seats), but the price in the US is not 8k, that's in Canada. It's $5600:

https://www.alexanderbmwaccessories....Shoppable=true

And it costs this much because it comes with these parts:
Part #
18305A6A720
BMW M Performance Exhaust System in Titanium
18305A86350
BMW M Performance Exhaust Tips in Titanium
51125A46B54
BMW M Performance Rear Diffuser in Carbon Fiber, MPP Exhaust
18305A6A6A7
BMW M Performance Tailpipe Finisher Module in Titanium

The diffuser is needed to accommodate the different exhaust tips arrangement.

I supposed, based on the parts above, it's an axle back exhaust (so pretty much a cow udder replacement) with the tips.

It is actually $10,310 installed at port. You might be mixing this up with the f87 part as a part only, which last time I checked was listed as the part for g87. I'm just guessing where the mix up came from, but either way it's $10,310

If you are willing to spend that kind of money, get the Akrapovic and the diffuser of your liking. Will look, perform and sound better.

The Valvetronic full catback stainless or titanium is a far more economical option and equally as good, performance wise.

The website is misleading, if you were to select all the parts and add it to your cart its 9k + install. 5600 is just the muffler.

Yep, when you click “Select options “ it adds all of the parts. It’s $7660 at my dealer apparently

Gotcha, thanks guys who pointed it out.
Not for me, but I understand who likes the looks.

Watched a video and the sound wasn’t night and day different.

Valvetronic's catback is far superior and much better (and realistically) priced.

Yeah, me neither. I honestly don’t understand what BMW was thinking with most of these parts. But happy for the folks who like and can afford them and get the added warranty.

You usually bring them up, are they the same setup with quad pipes stacked?

Never said it did. The M Performance exhaust is an overpriced barely upgraded from stock exhaust. Personally, its junk (you are paying for tips and a diffuser, very little in the way of performance improvement).

It’s its biggest selling point.
If it’s not for you it’s fine. It’s for some.

Not sure what that means. Just wanted to provide info on quality and price. If its the stacked look os the sole reason one is going for, then overspend away.

300CPSI sport cats, EL midpipe + M performance axleback would be my dream setup if money was irrelevant. Hoping a 3rd party company creates a MP exhaust lookalike for a fraction of the price.

I hope so too, but I'm not sure I have the patience to wait. Whenever I get my allocation, I'll be seriously considering the MP exhaust. I know it is visually controversial, but I personally love the look. I'm going for an aggressive, slightly over the top aesthetic.
