Incredibly easy to install. Like a matter of minutes -- no jack, lift or anything required. Works exactly as described. Dead simple with no can-bus wire tapping required like other valve controllers.

Works great and extremely easy to install!

Installed in seconds and works as advertised!

Excellent, Just 5 min to fit, lovely burble from exhaust with flaps open

Great bit of kit!! Took 2 minutes to install & dose what it said on the tin. The Team responded to my questions in quick real time before & after purchasing, thank you for that. Very happy with the product ☺️ Thanks again. 👌

Thx for everything

I have tried several different products to control the exhaust valve on my 2020 GLC 43AMG. This Mode 11 exhaust works perfectly. My wife can use my car and it starts with the normal valve closed position and she does not have to even think about how loud the exhaust can be...but when I turn the car exhaust valve to the open position, it gives the perfect amount of noise that makes driving fun...

Excellent. Really easy to fit

Works like a treat. Easy as to install Sounds angry

Great product! So easy to install and work straight away.

What a fantastic product, so easy to install and a true plug-&-play module.

I have been looking for this Open or Close setup without the need to include all the other settings like other companies offer, this simplifies everything!

High recommend this to anyone that's sitting on the fence.

Ordered it for my G81 to just have more flexibility with the flap controls. 11mode package arrived fast and well packaged. Installation was easy and fast. With the right tool to get behind the clip of the original cable mounted to the flap control unit, its done in 5 mins for both sides in total. The remote control works perfectly. The sound difference is def. there, probably the best value for money if you want to get a bit more sound out of your G81 without going after the exhaust itself!

5 minute install! there is an improvement. It should have been like this from factory! Installed on my 2024 Cayenn Turbo GT
