Very easy to install once you figure out where to press down on the factory connector to disconnect. Works as it should and it is way louder compare to factory M setting

It really only took minutes to install, and I was able to sync the keyfob to my garage door buttons in my M2. And it sounds great - not too loud but very noticeable! Highly recommend to anyone who doesn't want to alter their exhaust in any way but wants some more sound!

Made a huge differance on my c43 amg. Well worth the money!

Super easy to install, love that there’s no need to run a wire like some of the other brands. Plug and play, as easy as can be.

Phenomenal product. So easy to install, less than a minute each side.

It’s honestly impressive that such a small thing can make such a noticeable difference. 11Mode’s design is really simple but that’s the beauty of it. No fancy boxes or extra wiring needed like other brands. Just splice it into the factory connections and done. Takes less than 5 minutes and absolutely wakes up the exhaust note that the factory hushed even in Sport+ mode. I’m also a big fan of the fact that it reverts back to 100% stock function when you shut the car off. I have a habit of leaving the valves on my previous cars wide open which is enough to wake the dead at 4am when I cold start and head off to work. This takes care of that issue completely.

What a great, easy to instal unit! I was able to get everything together in less than 5 min. The exhaust is definitely louder than the factory sport mode option as it maintains the valves in an open position 100% of the time. It’s perfect with my resonato delete and exactly what I was looking for!

So, Mercedes AMG guys with performance exhaust (at the valve install):
My GLC63S install was easy, but Mercedes makes it tougher than it should be, but once you get to the install, it makes sense. 10min max.

“...but...I have OEM performance exhaust!”

Most of us do. This makes it PE+. Always open valves, not the muting by Mercedes. You’ll feel and hear it through the gears. You’ll notice it at stops. It’s pretty decent upgrade and worth the money and wait.

The remote? I mounted it. It’s now part of my start-up routine.
…that’s about it. Well worth it if you have our AMGs (smile HARD if you have a V8). 😁

Installed the 11-mode exhaust valve controller on my Revuelto and couldn’t be happier. The product works flawlessly and gives great control over the exhaust sound in every driving mode. Customer service was excellent from start to finish—quick, helpful, and professional. Highly recommended

Easy and simple to install, took me less than 30 secs. Didn't need anything complicated and this delivered.

Works as described and very easy to install in a Portofino.
Sound is the same but without the annoying cutoff at low speeds/throttle.

Fitted an 11 Mode exhaust valve controller to my BMW X5 G05 and it works really well. Gives you proper control over the exhaust valves and makes a noticeable difference straight away. Install was straightforward and the unit does exactly what it’s meant to. Happy with the product and the service — would highly recommend.

Super easy install and works great very happy with it sound is just perfect. Highly recommended for anyone not sure about getting one. Just do it .

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.
