Quicksilver Sport Side Muffler Deletes w/Sound Architect for Porsche 911 GT3 / RS 2014-2019

The Quicksilver exhaust upgrade for the Porsche 911 GT3 and GT3 RS focuses on improving sound and weight without compromising the factory engineering. After extensive testing across multiple configurations, Quicksilver confirmed that the OEM manifolds and catalytic converters already deliver efficient performance. Replacing them would require removing emissions components, which was not part of the design goal.

Attention shifted to the rear silencer, a key component in the GT3 exhaust system. The factory unit features a lightweight construction with a dual-path internal design that controls both quiet and high-output modes. It also plays a role in producing the signature high-revving tone near 9,000 RPM. Collaboration with Porsche Motorsport reinforced this approach, as many European Carrera Cup race cars continue to run the OEM rear silencer due to its durability, cost efficiency, and integration into the rear crash structure.

The most effective upgrade comes from replacing the factory side mufflers with a precision-engineered tube assembly. This system retains factory-style valve control, allowing you to adjust exhaust flow directly from the cabin. Installation is fully plug-and-play, with no additional modifications required.

Key benefits:

  • Over 30lbs of weight reduction compared to stock components
  • Retains factory valve operation for full control of sound levels
  • Straight-through exhaust flow when valves are open
  • Preserves daily drivability with adjustable volume
  • Enhances the high-revving GT3 sound profile with added intensity

With the valves open, the system delivers an aggressive tone with crisp pops on deceleration. Close the valves, and the car returns to a more refined sound for street driving. This setup gives you flexibility without sacrificing reliability or factory integration.

Why Purchase Quicksilver?

Quicksilver has been doing this since 1973, and it shows. This is a brand enthusiasts trust because they build exhausts the right way. Every system reflects serious attention to detail, from the welds, material used and the sound their systems provide. You get an exhaust that performs as expected, and lasts. If you care about how your car drives and how it sounds doing it, Quicksilver makes sense.

Note:

  • This system does not fit the 991.2 with OPF filters
  • Quicksilver orders usually take about 2 to 3 weeks once placed. The system ships directly from Quicksilver’s UK warehouse. To keep things straightforward, pricing already includes all applicable tariffs so there are no surprises when the system arrives.

Fitment:

  • Porsche 911 GT3 (991.1 / 991.2) 2014-2019
  • Porsche 911 GT3 RS (991.1 / 991.2) 2016-2019
