Designed and constructed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovič dB reducer (Titanium) is aimed at driving enthusiasts who need to keep the noise of the exhaust within approved levels during track-day use. Made from high-grade lightweight titanium, the dB reducer works like an additional muffler to allow extra expansion of the exhaust gases. It is easily fitted by simply removing the Akrapovič tailpipe set and then mounting the dB reducer in place. After installation, the Akrapovič dB reducer (Titanium) reduces dynamic sound levels* by approximately two or three decibels** while still retaining the unique Akrapovič sound and character. It is designed to fit and reduce the measured dynamic sound levels of all Akrapovič systems for the Porsche 911 GT3 (991) and GT3 RS: the Slip-On Line (Titanium), Evolution Line (Titanium), Sports Cup Line (Titanium), and Evolution Race Line (Titanium). The Akrapovič dB reducer (Titanium) is also totally compatible with the optional Akrapovič carbon-fibre diffuser, which is available for the Porsche 911 GT3 (991).
The Akrapovič dB reducer (Titanium) fits also to the stock exhaust system of the 911 GT3 (992) and GT3 RS (992).
*Dynamic sound levels apply to a moving vehicle and not the volume from a static vehicle.
**Noise reduction value is relative (or may vary) due to various noise-measuring methods used and external conditions at different racetracks.
