Question: How to improve the original Porsche 911 exhaust?
Answer: Reduce the weight and enhance the sound.
• Weight reduction:
Manufactured from Titanium and T304 austenitic Stainless Steel, the QuickSilver exhaust is less than half the weight, and this is removed from the very rear of the car.
• Enhanced sound:
In Sept 2018 the new WLTP (World harmonised Light vehicles Test Procedure) was imposed as a result of the VW emissions cheating scandal.
The WLTP rules compel all car manufacturers to ensure that their vehicles comply rigidly with worldwide harmonised noise regulations. The practical result is that cars manufactured after this date are significantly quieter. And... the simultaneous imposition of particulate filters makes them quieter still.
For concerned citizens this is desirable, but for enthusiast drivers the sound is an important element of the experience and almost no one wants a silent Sports Car (even electric vehicles are being saddled with artificial soundtracks).
The QuickSilver 'Sound Architect' exhaust for the Porsche 992 should please all enthusiasts with it's bass-heavy presence and rising note under acceleration - With nice turbo wheezes it provides a sound that makes a great car even better.
*As pictured, our system also fits cars with the sport option rear valance.
REASONS TO BUY
• Easy Installation retaining Porsche's Variable Valve mechanism for full OE compatibility:
From the factory, Porsche's new 992 debuts a new linear valve mechanism to provide infinitely variable exhaust sound. This is far preferable to the previous valves 'open or closed' that provides such an unsatisfying experience.
QuickSilver's Active Valves are created to perfectly replace Porsche's OE valves, retaining all original functionality via the button on the steering wheel.
• Reduced Weight
Factory Exhaust 10.2 kilos 23 lbs
QuickSilver Exhaust 5 kilos 11 lbs
• Enhanced Sound
Super Sport mode is actually quieter standing still and at lower cruising speeds than Sport Mode.
When the vehicle is in Sport mode and at lower speeds the exhaust delivers a wonderful range of pops and gurgles on the down change and over run. This is mainly due to the cars ECU deliberately exaggerating the drivers actions and the valves changing position to suit.
In Super Sport mode however maximum performance supersedes this by switching to a much leaner ECU program that favours increased flow so the valves stay open more and throttle response is increased.
