It works! Your car sounds throatier.

Fantastic bit of kit. Installed in about 30 seconds and no issues so far. Keeps the valves open to make the car sound like it should from factory - a deeper note at all times even in comfort, sweet sound under acceleration and get the occasional burbles too. If you’re ordering to the UK then as others have said, be aware the import fee is around £50 on top.

It perfect!

Fitted this to my brand new G82, was great for a few weeks and then it threw an engine light, checked the code and it’s the opf- took this off and ran it for a couple of weeks and the light went out.
The car went to BMW yesterday as they could see the fault even though the light had gone out, they ran their tests and everything is perfect and under warranty, no mention of this having been fitted!
Fitted the GO11 back on it today!

Super easy install, and gives the M2 a lil more growl!!

Works great. Wish it would default to open

Easy to install and sound is deeper
Very good modification for the price

After installed the car really has different sound more deep tone and much more burbled, i personally worth it rather than you change the whole exhaust system

Your exhaust valve opener worked perfectly from first start and Only took a couple of minutes to install.
From the moment I ordered till its arrival, which took about 2 weeks from Australia to Southern California, you kept me informed with tracking the entire way.
My BMW X5 finally sounds like it should. The right exhaust is fully open and working like it should have from the factory
Thank you to everyone at 11mode for the great product and outstanding customer service..
I highly recommend your product.

Controller livré en France avec un délai très raisonnable(prévoir quelques frais de douanes).
Installation très facile et fonctionnement au top👌

Hi
It works great I added down pipes which makes it more aggressive sound thank you.

Brilliant bit of kit, so easy to fit and does exactly what I wanted.

Amazing product. Super easy install took 10 mins.

Purchased this for my Mini S with the JCW Pro Exhaust. This kit totally replaced the horribly unreliable factory bluetooth controller and has given me full control over the valve again. Totally saved my sanity.

Ease of installation was not undersold - Product does what it says its supposed to do.
