As M60i owners we aren’t too spoiled when it comes to aftermarket exhaust choices. Sadly. My guess is that BMW really messed up this powertrain with the fancy manifold design, and on top of that clogged it up with so many environmental protection gadgets that it barely makes any sound at all… worst part is the European version (I happen to have one) sounds like a 4-pot diesel, mainly due to the extra OPF, which you don’t have in many other geographies. Pisses me off, tbh

I spoke to a bunch of distributors here in Poland, and they say companies struggle to invent anything to give this car a proper V8 sound. A few have taken up the challenge, though. There’s the dÄhler (Swiss), there’s Supersprint (Italian), there’s IRL LLC (American)

A bunch of companies are working on theirs (Valvetronic, for instance)

There are some Alibaba options from China (if you’re courageous enough)

Akrapovic doesn’t have one, and when I asked them, their response was not that far away from showing me the middle finger. Won’t buy anything from them ever. Period

There’s a Valvetronic thread on the forum - for guys considering a group buy

Happy hunting!

I re-read your post, and found I missed the bolded bit. What exhaust is that? Can you ask the dealer to provide some more detail or BMW product number? Last time I checked (mid-Dec), no M Performance exhaust was available for the M60i models (neither Germany, nor Poland)

Thanks!

Sharing another updates from Kies Motorsports about the installation of Dahler exhaust.

"Regarding the installation of the dAHLer exhaust system on the X6 M60, you are correct that some modifications may be necessary. The installation typically requires adding washers under the rear bracing arms to accommodate the size of the new exhaust. Additionally, there might be a need to slightly bend the rear bracing arms to ensure a proper fit, as the new exhaust is slightly larger.

If you have any further questions or need assistance during the installation process, please feel free to reach out. We're here to help ensure you have a smooth experience with your new exhaust system."

Does all of this present the potential for warranty issues??

I did catless secondary downpipes and there's practically no difference. There's more of a howl under throttle but outside the car, no one can tell I have done anything and why I have not made a video. I am debating of deleting the stock resonator and adding a x pipe.

I just installed the Valvetronic exhaust and like it a lot. It isn’t over the top. Very nice overrun and pops. Slight bit of drone at certain rpm’s and gears but not bad - wife has not even commented on it and she wasn’t even aware it was going on. Very it with flaps closed using valvetronic controller.

Nice! May I ask how much you paid for the installation?

I installed RedStar secondary downpipes today for my X5 m60i. Installation took about 1 hour, everything fits bolt on.
First of all, before ordering downpipes, I was pretty disappointed with the sound and Iconic Sound feature. I am coming from G63 and can confirm stock M60i doesn't have any sound at all and Iconic Sound feature is just a JOKE, however it is a reality nowadays. I test drove M5 G90 and it has all this Iconic Sound stuff to including artificial burble.

So what can I say after installing ONLY secondary downpipes. Sound increase is like 10% and you can finally hear some engine sound without Iconic Sounds feature. So there is finally SOME REAL sound. It reminds me of a very muted F90.

I will keep this since i don't want to go fully downpipe or cut the resonator. Maybe if some legit exhaust system come up, I will install it. I do not like valvetronic or dahler garage solutions since the car is pretty expensive and overall it is good.
