AKRAPOVIC TP-PO991GT3/BOX Silencer (Titanium) for PORSCHE 911 GT3 / GT3RS (991)

Developed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovic dB Reducer (Titanium) is designed for track days when compliance with established exhaust system noise limits is required. Crafted from high-quality, lightweight titanium, this component functions as an additional muffler, providing extra expansion for exhaust gases and reducing the measured noise level.

Installation involves removing the Akrapovic exhaust system tailpipe set and fitting the dB Reducer in its place. Once installed, the dynamic noise level is reduced by approximately 2–3 dB while preserving the characteristic Akrapovic sound.

The Akrapovic dB Reducer (Titanium) is compatible with all Akrapovic exhaust systems for the Porsche 911 GT3 (991) and GT3 RS (991): Slip-On Line (Titanium), Evolution Line (Titanium), Sports Cup Line (Titanium), and Evolution Race Line (Titanium). It is also fully compatible with the optional carbon fiber rear diffuser for the Porsche 911 GT3 (991).

*Dynamic noise level refers to the vehicle in motion, not static measurements.

**Noise reduction figures may vary depending on measurement methodology and track conditions.
