Aftermarket exhaust for M850i?

How you think about an aftermarket exhaust for M850i. Does it worth it? There're people saying you just have to have a tune and an exhaust. You can have more power than M8. It's interesting. How you guys think

Sounds about right. Exhaust + tune will yield very good power increases from FI cars

There are several aftermarket solutions for the M850i's exhaust and tuning. If I end up buying out the lease on my 2020 M850i I'll definitely be doing both.

I don't think there are many exhaust options. Last time I checked they were all for the m8 and not m850. But maybe there are some new ones now.

The exhaust will give you the sound bloozemanAZ is always looking for because he got the coupe over the convertible.

The tune will give you the power. It's like overclocking a cpu or gpu on a pc. They say exhaust gives you some power, but it's mostly bs. A tune is the only way to get the maximum power. However a tune will usually only give max boost if you use 93, 95 or race fuel and not 87, 89, or 91 fuel. Also a custom ECU tune will take into account any mods like a cold air intake or different engine mods to give maximum power.

A friend of mine in the UK has the AC Schnitzer exhaust on her M850i...and the diffuser which has to be fitted too - as otherwise the exhaust won't fit.

How would you say it sounds when you hear it live? Given exhaust sound is not a priority for me, it's still interesting to know how the feedback is from those who have it or have heard it on friends' cars. FI Exhaust is another valid alternative (for the M850i) to the unavailable Akrapovic. Also while most tuning efforts (not just in the exhaust section) may focus on the M8, it's great to hear there are some very decent options for the 840s and 850s as well.

Good to know as I almost commented that the AC Schnitzer exhaust is on my short list. I plan for their carbon diffuser as well as it is required to compensate for the quad exhaust tips plus it will remove the greyish abomination of a diffuser and bumper wrap on the car now.

Curious as how the exhaust sounds on your friends M850i. A video of it in action would be greatly appreciated if you could shoot one while she cold starts and then revs the engine. No need for a drive by but if possible that would be icing on the cake.

Indeed, an ECU tuned will make a huge different. I randomly saw this M850i clip and I love it! iPE did a nice job. The exhaust is way better than the stock one.

So slightly delayed, but here are a few videos of my friends M850i with her AC exhaust.

The cold start video is the car in Comfort Mode, but when revved you can still hear how intense it is!

They should all be working now - I hadn't confirmed my account with Vimeo (never used it before!).

Right, I've accepted I'm not cool enough to understand Vimeo, so have resorted to Youtube!

Hopefully these videos finally work!

The ACS exhaust requires the bumper and they are only compatible with each other. Also, it's $12k.

Total all above parts, shipping and installation plus tax.
$11,475.
