Service was great. Delivered quickly.
I am probably removing the device as it doesn’t make much of a difference in comfort mode and no difference in sport mode.
Works amazing and exactly as described
The product was plug and play and makes my car sound better when I need it. For what it is, it’s a littleeee pricey but whatever. I can’t do any other mods anyway
Works great on my car. You can tell a difference, when this device has been added, in all modes on my C63 amg S.
The controllers work as advertised, enabling the exhaust valves to be opened fully, or reverted to stock opening strategy; both modes at the touch of a button on the supplied remote. I suggest ordering a second remote to be kept at home as a spare. Easily installed on this car without removing any panels.
So easy to install. Simply unplug the original plug, plug in the 11MODE adapter and then plug the cars original connector into that. DONE!
Completely tool-less, 10 minutes installation, fully plug and play, no check engine light, no stored soft codes. Now with the new functionality, it's even better!
Brilliant product!! Installation time is 2-3 minutes per side and it will definitely have a deeper sound than the factory system. What I like the most is that it provides the same sound in all modes (not just sport or sport+).
I am satisfied and would recommend it to anyone looking for a valve controller.
Great product, plug and play made easy! Although the install was a PITA for the passenger side exhaust.
Instalation was quite easy. I din't have to even lift the car. Ofc it would be easier but it isnt nesecery.
The sound difference is noticable, espetialy in lower RPM ranges.
The only downside is that it dosn't have memory option and you have to reenable it each time.
Over all great product!
Opening the valves gives great extra noise at high rpm in the lower gears without needing to use M1 or M2 modes. I drive in manual mode more often than not now so I can get the max noise.
Install took a bit longer than stated, just because the connectors took quite a bit of force to click into place and I didn't want to break anything. All in all, very simple install.
It is really nice, even better than I expected, howeasy it is to install and how better the car sounds
Plug and play. No wires. Hassle free. Would recommend if you want your valves open in comfort/normal mode. In sport mode it is even louder paired with after market exhaust set up. When you turn off car it reverts back to OEM setting.
Comport mode noticeably difference from quite and refined to aggressive. The responsiveness is impressive to my Vw golf R black edition. I recommend this product.
Great addition to my car. This is a very nice piece of kit. Took less then a minute to install. Improves performance and the sound is awesome. I can now drive my car more in comfort mode and it still sounds like a sports car.
Easy to install but not that loud
It is best that you drive the car a bit more to evaluate as this is when you'll hear the difference the most. The role of these exhaust controllers is to keep the valves fully open all the time (no matter what drive mode) and throughout the whole RPM range.
The sound difference will all depend on the actual car and exhaust design as all different makes and models have different exhaust designs and how the car controls the valves.
The controller will get the most out of whichever exhaust system you have as the valves will now be fully open all the time instead of some of the time.
Super easy install, didn’t even have to remove exhaust heat shield, definitely wakes up the M60i
I think it worked out pretty decent compared to a 3000$ sport exhaust upgrade. Sounds louder ambiently and louder sooner. Little tough to install only bc of the anatomy of my2023 bmw X5 m50i the valve controlled was hard to get to but it plugs and play so not11mode fault. Pretty sweet and priced better than other brands. Came in about 2 weeks or less
Excellent product and easy to install, great value a modification on an RS6 C8.
