QuickSilver have done it again, taking the factory system, this time from the BMW M140i and looking at ways to improve the overall performance and of the sound for the car and the driver!
This time the driver was well known instagram and facebook blogger Jo aka Skullsandsnaps @skullsandsnaps
We removed several restrictive silencers in place of large bore stainless steel tubing.
Whilst integrating an easy to install electronic control valve to offer two distinctive driving sound modes. QS Sport and QS Stealth.
We are still here to send your system direct to your door.
