I have always felt that the stock exhaust on my M2 is way too quiet. My wife's Kawasaki motorcycle is at least twice as loud.

is there an aftermarket exhaust for the 2023 M2 that can switch from obnoxiously loud to super quiet? I can get away with the obnoxiously loud because my house is almost in a rural area. My nearest neighbor is 1/2 mile away. However, I do work in the city(at a large hospital similar to the Cleveland Clinic), so I can't have a very loud car when driving/parking in that area.

any suggestions appreciated.

Any non-resonated exhaust will do the trick. You have tons to choose from, just do your research as to the build quality and where they are manufactured.

A few come to mind:
-Milltek (I use their full catback, non res and its louder than any others I’ve heard)
-Active Autowerke
-AWE
-Eisenmann
-SuperSprint
-IRL LLC
-Dinan
-Evolution Racewerkes
-Akrapovic
-Remus
-FI
-Fabspeed
-Valvetronic (would stay away)

The list goes on. Figure out if you want just mid pipe or full catback.

Best of luck!

The above list should be taken with a grain of salt. It names systems that are truly junk to one step above junk yet labels one Valvetronic Designs (very high quality design and workmanship with absolutely no issues running over 700whp with it...and sounds phenomenal) to stay away from.

To respond respectfully to the OP, go with whatever exhaust you want but just make sure you have the valve controller installed. With that, you can run anywhere from stock when you need quiet to fully open valves when you want the sound.

Can you tell me which ones are junk or nearly junk so I can avoid them? If you don’t want to blast them here in public you can dm me the info. I wouldn’t have assumed any of these would be subpar. Appreciate any insight you can offer!

Valvetronic is Chinese white label. 0 quality in those. Most others labeled are made not in China. So yeah ok lol.

Every brand in the list has their fans & detractors. I have never seen anyone post a story about any exhaust system by a known brand fall apart, rust or have a detrimental affect on performance. Quality of sound is subjective so take anyone's opinion on quality (not volume) with a grain of salt. UNLESS someone says the system produces a drone. Some folks like drone, some folks don't. I am in the latter camp - it gets old, fast, on long drives.

Catless downpipes also increase the volume. Downpipes with "sport cats" are quieter than DPs without cats but louder than OEM cats.

As already mentioned by another poster, no resonators will yield the louder sound. But you risk drone.

I don't think I've ever seen an aftermarket exhaust that isn't at least stainless steel. So now you get into quality of the SS. Again, those brands, I've not heard anyone complain. There are titanium exhausts that are pricey - used to save weight & I guess for looks. They have a higher pitched exhaust note.

Next you get into quality of the welds. I've never heard anyone say "this brand's welds suck & leak."

Now you get into price. I think many of these exhausts are way overpriced. You can get nice sound & quality finish going with a more reasonably priced exhaust, so why go big bucks except for bragging rights.

I bought MAD's axle-back to pair with Dinan's nonresonated mid-pipe. I have the midpipe (incredible finish) but have not yet received the exhaust. MAD's scheduled release was 7/18 & they're quiet late. It looks almost identical to Dinan's exhaust, but is $700-800 less. I am annoyed enough by the delay & lack of communication that I'm thinking about cancelling my order & getting Dinan's exhaust.

I've used Active Autowerke's exhaust parts. Excellent fit & finish. They're not the most expensive, but they are on the high end. Made in USA, excellent customer service/communication & really good people.
Dinan - quality fit & finish, long history with BMW.
Remus - I don't like the sound of their exhausts. Lots of youtube videos on this brand. Quality - looks pretty nice to me. Pricey.
Akropovic - known for being loud, amplifying pops/bangs/burbles & to me, they sound very "braaaaapy" because of it. They are known for high quality. Very pricey, can't figure out why. LOL
Fabspeed - I had their sport cats on my F87. They threw codes & wasn't enamored with their finish. Not that they're bad, just another brand out there where I wonder "what's their differentiator? why pick them?"
Eisenmann makes quality stuff. German. Go figure!
Evolution Raceworks - I had their intercooler. I didn't think their welds were all that special. But it did the trick. They're known for quality.
Valvetronic is pricey for full systems. You can do as good, maybe even better, for less money. Zero reason to pick them at their price point vs others that are less. Nice finish, nice welds. I do not know enough about the brand to understand why Geighty7 says to avoid - not questioning his opinion/experience with that comment. I actually don't know. I do think he knows what he's talking about, as he provides a LOT of feedback & input on folks' questions.

For example, Valvetronic's axle-back with chrome tips is $2199. Dinan's is $2049. I'd buy the Dinan simply because of my familiarity & trust with Dinan's products and also why not save $150? Unnecessary to spend more.

Plus, I LOVE the tone Dinan gets with their exhausts. It's got deep note. Might not be the loudest, but I hate loud for loud's sake.

And I am the type where price really doesn't matter if the quality & results I'm looking for are there. I could spend the $4200 on that Italian TFL exhaust, simply because my motherland makes it & it's gorgeous. But all exhausts do the same thing & no one is gonna see it. So does it sound $4200 good? Hell to the nizzno.

MAD, Dinan, Active Autowerke - any of those do the trick for a lot less.

My last post here cause I am not looking to get into a pissing match. Valvetronic does not hide the fact that their product is manufactured overseas. Many brands are and it doesn't mean they are bad. Yes, sone are bad...but some are also of high quality.

Despite some thoughts and claims, Valvetronic products are not dropshipped Ali junk.

exhaust system is not like high-end chip technology. I feel sad for those spent tons of money just for branded stainless steels...I can image how those business works-they may call it culture 😔

I would say most important thing here is getting a valve controller.

Most of the G87 exhausts and midpipes are loud but when you say you want it quiet that’s the issue. In stock control the valves will open regardless if your mashing it. At least this what I have experienced if I floor it for an overtake my valves open regardless and queue laser dagger eye beams from the wife and -10 Booty points for the week.

I have the Miltek and it’s loud, had to have my valve spring adjusted due to rattle. Other than it’s been ok. If I did it over I’d just do mid pipes or go whole hog Akra with controller.

[sacowich]

I second the valve controller making the biggest difference.
I have AA downpipes and Valvetronic midpipe. The valve controller makes a huge impact on level of obnoxious.

Hey folks! Thank you all for the support in this thread. Respectfully responding to this we really don’t appreciate this uninformed slander of our brand. I directly say “uninformed” because you have not seen any of the recent press on Motortrend or any of our internal videos, showcasing our in-house development. We are working extremely hard to improve brand image and showcase what we can truly engineer.

Let’s take a look back when the G80 and G87 was initially produced. We were the first in the world to develop an equal length set up for the G 80 and the G 87. Well ahead of the competition and we produced videos showcasing the sound characteristics. Are our systems made in China? Yes absolutely, but everything is designed and engineered here in Pennsylvania to our specs and our quality levels before it gets sent from mass production. If we were just drop shippers, we would’ve failed long ago like so many other brands you see come and go in this industry.


Did we start this business by Dropshipping? Yes we did, but then very quickly, we found that business model doesn’t work and have worked extremely hard over the past three years to have our own designs, engineer and develop our systems in-house so we can separate ourselves from the competition.

Everyone is welcome to purchase whatever they like but we would appreciate some more respect when it comes to the effort and development we do for the community so we can offer the best product. Thank you for your time in reading this.

That’s a lot of words just to tell me you’re unhappy that I said your stuff is made in China and my opinion is that the quality isn’t up to par with your competition. Thank goodness for free speech here in the USA. Nobody is slandering your product so back up and be more professional as a brand, this post is sad and off putting as you beg for respect so you get more sales.

By the way…AA was the first equal length system, hence why it’s patended. Don’t worry, my little comment won’t deter your future business, this is just hilarious I ruffled your brand feathers

I’m no Valvetronic Design fanboi but what exactly does a product being made in China have to do with quality? What exactly are you implying here? There are many quality products made in China and some not so much, just like any other country. Many U.S. based businesses make bad crap. The quality of a product isn’t determined by which country it’s made in.

Our feathers are ruffled because I’ve created a team of people who are extremely enthusiastic about the product and who work hard every single day in order to put out the best possible experience for enthusiasts around the world.

No team will be able to bat 1.000 but we are getting better every day and working to provide enthusiast the best experience.

We look forward to the next time you interact with our product and have a more positive experience, reveling in all the quality improvements we have made. These improvements changing your opinion so you recommend our products to your friends. I’m looking forward to that day and that would make me very proud

Lastly, I reference in the post, “G80 and G87 equal length” not equal length as a whole!

If you're okay with a bit of cutting. I did mid pipes with the stock muffler and I couldn't be happier.

Valves Closed: barely noticeable increase on low throttle / street driving. On hard throttle you can tell there is a difference but it's not insane.

Valves Opened: you notice it all the time but on full throttle its pretty awesome.

This thread covers the product. Made in USA

it’s been several years since i have been in a M and toying the idea with some version of the g8X as a toy weekend car. As mentioned some years have past and a bit older now. i do still really enjoy modding my cars but a full system seems a bit out of my age.

my last M was a M8. i ended up just doing secondary catless downpipes, stock muffler. the car had 4 cats. i was more than happy with the change in volume and it kept a very clean note. Burbles were still there but nothing obnoxious

i am thinking to go with just someone’s midpipe and use a valve controller as others mentioned. i will be doing the occasion track day and unfortunately most of the days will have noise restrictions. hoping midpipe only will keep my from getting kicked off the track

when looking for a midpipe anything i should be looking for?
