BMW M3 M4 G80 G82 Quicksilver Centre Exit Sport Exhaust with Sound Architect
Unlike the OEM sports system, which barely delivered on acoustics, QuickSilver’s Sound Architect™ sport exhaust is a significant step up in volume, tone and valve functionality.
The system is offered in two parts: OPF-Back - for owners wanting to keep their car emissions friendly; OR with optional OPF & Secondary Cat Delete pipes (supplied with pre-programmed terminator connectors so the vehicle does not require remapping, with the ability to revert back to stock without a trace).
From factory the G80 / G82 is restricted by WLTP valve programming or ‘active noise suppression’, which requires the factory exhaust valves to close arbitrarily below 30mph (all driving modes), at anything other than full throttle input, and every time you lift off. Stifling the robust straight six soundtrack these cars are famed for. Pairing with Sound Architect™ provides the driver with 100% control over the sound, with valves open or shut permanently via the app without interference from the car. The valves can now also be opened in any driving mode.
QuickSilver’s system features a built-in resonated H-Pipe, for a punchy but smoother note without intrusive cabin frequencies; 76mm tubing all the way through and a total silencer bypass with the valve open - creating a wonderful soundtrack rich with crackles and pops on the overrun that delight the senses. With the valve shut the gasses enter a triple chambered pass, transforming the M4 into a more civilised beast, appropriate for early morning start ups or long motorway journeys when refinement is key. 101mm carbon fibre tailpipes fill the rear valance to ensure this exhaust looks as good as it sounds.bmw m
