Good but not great. I can notice a difference but i dont know that i would do it again.
bought this controller for my 8v.1 RS3 and it works exactly like the description says and has revived the sound of my car in day to day driving!
Great product. It bypasses the car setting and opens the valve completely while being in a comfort mode. The car sounds great.
Great product, looking forward to pairing it with my new Alrapovic full exhaust
Great product easy to install and makes a difference
Fa esattamente quello che promette.
A bassi regimi il suono è fantastico!
Excellent product!
The valve stays open, and the sound is perfect all the time. However, the remote control doesn’t work 🤪
Wie gewünscht nicht zu laut sondern ein angenehmes blubern mit original Abgasanlage
Works great! Love the garage door integration. My X5 finally sounds like it feels, and when I'd like silence, mainly on highways, it is at the press of a button.
Better than I expected. A deeper, aggressive exhaust note at lower revs that is very pleasing in daily commuter-type driving.
Works great, just need to understand the red tab. You need to push up on a little grey tab below the red tab while pulling down on the red tab. The red tab will then slide down. After the red tab is down all the way. Then on that same grey tab under the red tab push up the grey one up and pull off the connector. It took me about 20 minutes to figure out the grey tab truly is the release tab and the red is locking. But once you figure that out the second one comes off in seconds.
Installs and works as advertised…sound is amazing. Install was incredibly easy…it took longer to get the car on the lift than it did to plug them in. Great product from an initial experience…assuming it continues to work, would recommend these to anyone. Before installing a new exhaust, buy these…it’s so easy and relatively inexpensive it’s worth it to try first.
Paired it with unitronic midpipes - sounds way better than stock. Highly recommend 11mode. Even sounds good in comfort, where before it was super quiet. Great product and customer service. Exceeded expectations. Thanks!
this is by far the best plug and play device in the market. It made a huge difference.
Very easy to install and works perfectly.
Fantastic! Easy install and great product. Easy to use and makes my car sound great. No messing with wires.
Great product, very easy to install Took only about 25 min including displacement of the shield, and it makes a day and night difference, and love the freedom to close the valve anytime I need it to be quiet, works great. Highly recommended product, definitely getting it for my X7 as well
Plug-in play!
Great innovation, no wires no headaches. Just works great.
Excellent upgrade for the noise exhaust! Sounds way better now!
Product quality brilliant, so easy to fit, took me less than 5 minutes. If I'm honest though, on my particular car and after import duty it didn't make enough difference to my car for the price.
