After other positive feedback from M2 G87 forums on the 11Mode exhaust valve controller, I decided to order one. It came from Australia to the UK in less than a week and was very easy to fit. I have had it on the car for over 2 weeks and it has worked perfectly every time I have used the supplied remote control to open and close the exhaust valves. It makes the car sound much better and gives you the option of letting the car control the exhaust flaps in its stock format or switching them fully open for maximum sound. I would highly recommend this product.

I've had the 11-mode exhaust mod for two weeks, and it works as expected. It's a time-saver for those who want regular mode performance with a Sport+ sound. If you're not a mechanic or handyman, this is the easiest DIY mod, taking just 25 minutes to install.

Works great on my CLE 53 AMG

Todo perfecto, funciona 100% y se escucha más .

Way better than I expected, it works like it should, without all the long, tangly wires that the other valve controllers have. Also, GREAT customer service.

if I could give this company 6 stars I would. Price is half of what other companies charge, shipping cost was also very reasonable and package arrived super fast. Took me 5 minutes to install, with other companies there is a wiring harness that has to be installed that is time consuming. Now I can drive in strada mode and listen to the exhaust symphony. Thank you 11mode!!

I was unsure about the item as it had less wires and the remote box in the design. Decided that I’ll give this product a go.

After paying my import charges and getting it delivered, it only took a few minutes to install the product. I’ve been running it for just over two weeks, although I have not made any other changes to the OEM exhaust and turning off ASD. When you open the valves it sounds so much better in any mode!

Happy with the investment and chance investing on this device. Totally happy with it and would recommend this to other owners.

Thanks Mode11

This is a great and easy mod to make a subtle change to the exhaust note. Not loud and brash, just more of how it should sound! Company communication and shipping was really good.

The controllers fit like a glove, buy most important work perfect so far. Very happy with the product. Shipping was lightning-speed (Mexico City). Greatly recommended and fully no-trace removable for warranty or car-sell purposes.

Maybe just for improvement purposes, will be great that they keep memory of last setting (I know there may me a brief self-test of the car at startup) as nowadays there is so much gadget intelligence that a memory or microcontroller could very cost-effectively do the job.

As stated by other this is a extremely easy product to install, my only issue was hand space with the passenger side plug.
Now my Tiguan has more noise in any mode. Can not wait to have the middle res removed for even more increase in fruity noises :-)

So easy to install, no wires to route and hide, to say it took ten minutes to install would be exaggerating as it was probably more like five.
The noise it makes is completely different, it’s deep and raw in comfort mode, burbles are exaggerated in M mode, but I can still make it quiet so I don’t annoy the neighbours, too much.
Really good bit of kit, easy, effective and cheaper than a lot of the competition.

Super simple install that I did with no tools, without jacking the car up. Was able to get to the connectors and installing without issues. Took a whole 2 minutes start to finish. The unit works as described. Pressing the top button opens the valves completely, while pressing the bottom button retains stock functionality. Design of the units that plug into the stock valves is nice, because the the little bracket it comes with basically installs on itself.

Very easy to install, and also very easy to use. The car sounds great in all modes now!. Best upgrade to the car sounds far!

Fantastic product, easy to install, and even more so if you use a car jack to slightly lift the car. On the RS3 8Y pre-restyling, the sound difference from low RPM up to around 3500 RPM changes completely, since the valves in the stock version never fully open. The sound of my car has finally improved at low revs and I'm absolutely satisfied. The price-quality ratio is unbeatable.

These valve controllers really open up the exhaust and give me the sound I was looking for!
