The Akrapovic titanium dB reducer for Porsche 911 GT3 RS (2014–2020) is a lightweight, application-specific sound attenuation accessory made from titanium. It is offered as a direct-fit component for the specified GT3 RS model years to temper exhaust volume when a lower decibel output is desired while retaining the exhaust system's fit and materials consistent with Akrapovic's titanium construction for that vehicle.
