BMW M2 Competition (2020 F87). There are lots of exhaust valve controllers out there that require wire routing, multiple button configurations etc. I researched all of them. As a car guy all you want to do is to be able to open the valves and enjoy how your car should really sound. 11MODE should be your only choice. Installation could not be easier and it just works. Take 10 mins install and enjoy!!!

It took 5 minutes to install and it works perfectly. The sound is amazing.

Love this device. So easy to fit - literally took 5mins on my garage floor. Gives a lovely tone to the engine without being OTT. Just watch out for the import duty. I wasn't expecting it, so the extra £40 ish stung a little bit!

Literally transformed the sound on my MH M340i, for how much it costs vs a complete exhaust system and voiding warranty and the hassle it’s worth every pound. Took literally 2 minutes to fit as well!

Thanks for the Great Support and fast delevery.

Great product, easy to fit and works well.

Einfach zu handhaben, funktioniert gut

Great service and postage was fast. Just wish the heat wrap came with it or was told about it prior.
Apart from that 10/10

It was easy to fit and does everything it said it would

Happy with my product , very easy to fit and does exactly what they say it will do . My BMW sounds much better now

Despite some doubts, this product did exactly what it said it would on my RS4. Easy and quick to install, it works instantly. It does make a recognisable difference when the flaps are opened.

LOVE IT, ONE OF THE BEST UPGRADES

Easy installation and affordable! Great sound! Highly reccomended!

Works great easy to install love it 👍
