Easy to fit, literally takes seconds.
And it’s definitely louder. Worth the purchase.

Easy to install works

This should be original from Audi.

Awesome bit of kit. It literally took me 3 mins to install on both exhausts. Simple plug and play. The units appear to be well designed and built. Very easy to use and the difference is just what I wanted (to have the sport plus sound whilst in comfort mode).

Superior product and customer service!

So far so good. Easy to install, makes a noticeable sound difference. Good bang for your buck until you do a full sports exhaust.

This product does exactly what they say. The change in the sound depends on what vehicle and exhaust type you have. So easy to install. I did mine in just a few minutes.

Me salio excelente gracias por esa buena creación

Was not happy that my BMW X5 right side exhaust had the flap closed unless in sport mode

Does the job that it's supposed to do

Easy to install!
It does the job

Fantastic, 4 clicks and you’re good to go.

Super bedankt, systeem werkt prima.
Makkelijk kunnen monteren.

Biede afstandsbediening werken ook.
Geen storingen.

Ben er superblij mee.

Thanx 👍👌

I was shocked at how much of a difference it has done , genuinely surprised. My face lit up when i first gave the throttle a rev. For not even a fraction of a cost of a new exhaust or even a downpipe. To get a much raspier tone. Not going to lie. Im in the UK with a right hand drive model. The left side original controller was a little difficult to remove compared to the right. Very happy customer

Shipping was great, works amazing and is so easy to install, makes my bmw sound so much better
