BMW M4 upgrade with full M-Performance (MPE) style sport exhaust and carbon fibre diffuser

June 27, 2022

QuickSilver and CarbonWurks present the G8X Sound Architect™ Exhaust. Featuring the iconic MPE-style V-configuration tailpipes paired with full pre-preg carbon diffuser and exhaust tips.

 

 

Option 1. Exhaust System and OPF Delete Pipes


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.

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.

Option 2. OPF Delete Pipes Only



For customers seeking the ultimate sound and performance QuickSilver’s modular OPF & Secondary cat replacement pipes got the G80 / G82 will deliver! 76mm mandrel bent tubing removes the restrictive filters and 600 CPSI secondary catalysts providing sharper throttle response, stunning definition and tone with increased projection.

CAD modelled to suit the QuickSilver OPF-back MPE system, QuickSilver quad system or OEM exhaust.


What’s more? With QuickSilver you don’t need to remap the car! Our OPF delete sections come as standard with pre-programmed terminator connectors which are plugged in to the OPF filters differential pressure sensor monitor. This means the ECU cannot detect the OPF’s have been deleted and the dash remains error code free! Nothing is logged on the ECU and the car is reversible back to stock without a trace. 

Option 3. Rear Section Only

With this option you retain your OPF filters for emission purposes but replace the mid section with our X-pipe and the rear section for the MPE style setup. The rear section also comes the Carbonwurks diffuser kit.
