The remote control does what it's supposed to. At least it did for the three days the controllers lasted.

Super einfache Installation und schnelle Lieferung

I love it. For me personally, I did not want a too loud exhaust, and using this makes the stock exhaust the way I wish it was from factory. Easy installation, did not even have to raise my vehicle. In the future, if I ever do get a exhaust, I know this will give me the tones that I prefer.

Awesome company, even with tariffs I still got the part in a relatively quick time. Plus part works amazing.

Works as advertised. The controller installation was a breeze. Remote control is responsive; one press of the button is all you need to enjoy the new exhaust's notes.

Simple install - took two minutes. Awesome results! No real need for an exhaust upgrade.

Had it installed on my M850i gran coupe. Definitely gives the car a deeper, tone once you click the remote and the exhaust flaps are open. Before I got 11 mode, I was able to change the engine sound of the car by going into the infotainment and selecting “sporty” under engine sound. This opened up the exhaust flaps and gave it a deeper tone but from what I understand, the exhaust flaps do not stay open even with sporty engine sound turned on or if you put the car in sport or sport plus mode. 11 mode is supposed to keep the flaps open 100% at all times, when you select the flaps open feature and the car is on. Just wanted to give clarity about that.

Super impressed how easy to install and how well these work with just adding this between the connectors. This really opens up the meisterschaft exhaust on my 2019 x5 50i. And when closed to stock it's perfect with the family to quiet down the sounds. Pairs good with home link too! Hands down!

Super easy install and was able to program the home link buttons to work the valves.

Installed this morning and seems to work as advertised. I can't tell a difference when idling in race mode but can while driving and gears are shifting. In eco or comfort, the difference is noticeable at idle or driving.

I was really impressed with the 11Mode I installed on my 2025 BMW M440i Gran Coupe. It really opened up the sound and tone. Very easy installing, took less than a minute.

I installed these on my 2019 BMW M5, very simple plug and play. I wasn't interested in exhaust controllers with a separate box that required wiring to work. This kit makes all others obsolete. Seriously. I even paired the supplied remote with the Homelink buttons on the rearview mirror to operate the exhaust flaps!

So far so good. Package arrived great. Wished the weather shielding on the wires goes from end to end. Mine came with a gap exposing the wires.
