Further Information
QuickSilver's sport side muffler deletes for the Porsche 911 GT3 and RS (991 Gen 1 and 2) replace OE side mufflers with precision tube assemblies featuring integrated Sound Architect™ valves. This system amplifies the natural character of the original engine sound while delivering significant weight savings and switchable acoustic profiles controlled via the factory cabin button and driving modes.
After extensive testing, QuickSilver determined that the OE rear silencer design is exceptional and left unchanged. The focus instead targets the side mufflers, which respond perfectly to this modification approach.
Key Features:
- Sound Architect™ electronic valves operate seamlessly via OEM cabin controls
- Over 30 lbs weight reduction without chassis modifications
- Plug-and-play installation with no additional modifications required
- Two distinct acoustic paths: civilised note with valves closed, aggressive sporty character when open
- Engineered to emphasize the 9000 rpm shriek and engine crackles
- Maintains factory safety standards including rear crash-zone integrity
Includes:
- Sport side muffler delete tube assemblies
- Integrated Sound Architect™ valve systems
- All required installation hardware
More aggression. More control. More weight savings. Built for the 991 GT3 and RS.
