This Mountune SSC is very effective ! No whistle at all with it :)
Excellent quality and fast service
The SSC is a very nice manufactured part, Mountune quality skills. Even with the Mountune induction kit and dump valve on my RS, the difference is lightly audible with SSC. The SSC installation is really not easy because of the f..king access to the circlip. After 1 hour of hard fight with the circlip, I made it ✌. But once you got the circlip out, it gets 5 minutes to install the SSC. Be strong, you can do it !!!
