The controller exceeded my expectations love the sound with the valves completely open when I choose

I just got the 11mode for my G80 M3 and it sounds great. I get to keep the OEM setup while sound a little louder which is perfect. Install was quick and easy , plug-in-play!

This is best bang for the buck in terms of upgrades. The car sounds glorious now.

does whats its supposed to do and very easy install .

Literally installed both control module in like few minutes and what do I get? A stress free no cut no 2000+ cost but unleashed what this engine should sound like. Love it!

I was hesitant to purchase. Didn't know if it would make a difference or not. Didn't want it to throw any codes either. 5 min install. Can open valves in GT mode now. Remote easy to operate & quickly responsive. They already fully open in Sport or Sport + because of AMR upgrade . Great product. Purchased April 29th. Delivered May 12th.

Great product, easy to install and makes a beautiful noise

Absolutely amazing….what a difference, it does exactly what it says it does.

Works well for my 2023 BMW 430i X-Drive. If I start the car in comfort mode and wait a minute or so I can hear the flap close. Then I pull out my 11mode controller and can hear it open with a nice deeper sound. I then switch to Sport Mode. I still wish my exhaust was louder, but I'm glad the flap is fully open now. Thanks 11Mode! Took 30 seconds to install, and loving it!

Great product! Easy installation. Shipping was fast and updated daily

You couldn't ask for an easier installation! Works flawlessly. No codes. Received the shipment from Australia to US in about 10 days.

Love it 🥰
Work great sound is way better.

Fantastic quality well made works well oz to Scotland very happy with purchase.

My social media was swamped with this product which made me look into one, and boy I’m glad I did! I contemplated ordering one for a long time, and then decided to treat myself for my birthday. From order point to receipt was about two weeks, which isn’t bad from Australia to Northern Ireland! Be aware of the customs charge when imported into the UK. The product arrived in a professional looking box with a thank you card and a couple of stickers. I took the valve controller out the box and had it installed in about a minute. The difference in sound, and the control you have is great! I love it! My wife called me childish and sad, but I don’t mind, I love the sound of my car now and the fact I can turn it on or off asI please! Highly recommend!

Great Product !!! Easy Install. Did what it was supposed to do. It shipped from Aus and was at my door within a week. What's better than that.
