Description AKRAPOVIC TP-PO991GT3/BOX Reducer dB (Titanium) for PORSCHE 911 GT3 / GT3RS (991)

Designed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovic dB Reducer (Titanium) is intended for track-day enthusiasts who need to maintain exhaust noise within approved limits. Manufactured from high-grade lightweight titanium, the dB reducer functions as an additional muffling element, allowing further expansion of exhaust gases and reducing measured sound output.

Installation is straightforward: the Akrapovic tailpipe set is removed and the dB reducer is mounted in its place. Once installed, dynamic sound levels are reduced by approximately two to three decibels, while preserving the distinctive Akrapovic sound character.

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