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.

Love your product, makes my X4M sound a lot more aggressive! I love it. Super easy to install !! Only took me 5 minutes!! Highly recommend it !

I did not believe 11Mode valve controller was real and so easy to install at the start, however, I was surprised how quick it arrived and how easy it was to install it on my RS6. No stupid manuals, no hours of cutting wires and figuring out how to connect them. 2 minutes under a car, in a public parking lot, no special equipment needed and it just worked - right from the start. I am positively surprised and amazed. Fantastic product, 11Mode. Hats off!

Can really notice a difference on my stock exhaust especially in eco and comfort

Great product as advertised, installed today in 5 minutes. Exhaust sound in stock mode was to quite, now in stock mode it's louder then in the M modes. Love it!!!

I would like to take the time to express my most sincere gratitude for the 11mode customer service team. I recently had a malfunction with the product installed on my vehicle so I contacted the company for support. I was immediately contacted with detailed troubleshooting instructions, forthcoming support, and excellent feedback. They were extremely responsive and helpful and went above and beyond to ensure I was satisfied with the outcome. Not only is the 11mode valve controller an excellent product, it is the customer support and attention to detail the company displays that will ensure they will have longevity in this industry. 1000% recommend this product and this company.

Extremely easy to install, took 10-15 minutes and it works perfectly! Car sounds much better with the valves fully open

Absolutely love the 11Mode exhaust controller
