How to give your BMW M140I or M240i the best sound with a QuickSilver Sport Exhaust

We demonstrate how to transform the sound on any BMW M140i or M240i with our Sound Architect™ Sport Exhaust. These full systems allow the driver to open and shut the exhaust valves at will enabling two very distinct exhaust sounds. The electronic module included only requires a 12v feed, usually a cigarette-lighter socket. It’s Bluetooth controlled on the driver’s smart device, and pairing takes just a minute. Built to suit every driving environment our system suits both OPF and non OPF vehicles.
