The original exhaust sound is more luxury than sports providing a silent cabin much of the time. A great achievement, but probably not satisfying for the target market's enthusiast driver. Many think that the V8 may sounds even better than the W12, due the deeper presence of the V8 engine combined with the fast-shifting close-ratio 8 speed gearbox. Whilst driving in D (where the revs mostly stay below 2000 rpm) the QuickSilver has a deeper note and within the cabin the sound is as quiet as the original system > when the customer shifts to S (and revs climb above 2000 rpm) the exhaust sound comes alive and rewards the driver with the full V8 symphony. There is also a significant weight saving over the OE system of 6Kgs. The QuickSilver system retains the original 'Figure 8' exhaust trims and is a direct replacement that requires no modifications. Installation time is about 1.5 hours.
Lighter weight and more efficient flow with a noticeable improvement in turbo response for even more exuberant acceleration.
The system removes the intrusive valves giving a more old fashioned elitist sound with more presence throughout the rev range.
