Easy installation 5min
And fits and works perfectly

Device was easy to install and pretty awesome I enjoy it.

Easy install. Adds noice

ottimo prodotto,abbinato al Down pipe,fa un ottima diffenza

Installation was fast and straightforward, and the sound difference on my 2026 M4 is night and day. What really impressed me is that it delivers this level of sound without requiring any exhaust modifications. If you want aggressive sound with a clean install, this is a no‑brainer.

2 minutes for install and the remote does its job every time I want the valves opened/closed.

Happy with you delivery

素人でも取付簡単で良い音になったよ！

Easy to install, and does what it says on the tin, allowing sporty noise no matter the mode setting in my MK8 Golf R. Happy as!

Great product works well. I would highly recommend

I don’t think install could be any easier, and I don’t think I could be happier with the sound. Great purchase.

Well engineered product! Would be worth highlighting the specific considerations from the support articles when shipping to a Mercedes Benz, I initially thought mine wasn't working properly and it took a bit of research to find the specific article which explained how operation differed on a Mercedes.

Exactly what I was looking for. Install took about 5 minutes — just unplug and plug back in. The cables are nice and short, tidy, and don’t move around, so everything stays clean.

Way better than the Milltek valve controllers I had on my M3 — those had 2m cables that were awkward to hide and just looked messy.
