AKRAPOVIC DB REDUCER (TITANIUM) - PORSCHE 911 GT3 RS (991) 2014 - 2017 SKU: TP-PO991GT3/BOX

Here are the main benefits of the Akrapovič Titanium dB Reducer (SKU: TP-PO991GT3/BOX) for the Porsche 911 GT3 / GT3 RS (991, 2014–2017) — and a few caveats you should keep in mind:

Benefits & Features:

1. Noise reduction for track / regulatory compliance
   The primary purpose is to reduce dynamic (on-move) exhaust noise by about 2–3 decibels while preserving the characteristic Akrapovič tone. 
   This is especially useful when attending track days or circuits that impose dB limits.  
2. Lightweight titanium construction
   It’s made of high-grade titanium, which offers good strength-to-weight ratio. 
   Because titanium is lighter than typical stainless steel, the weight penalty of adding the dB reducer is minimal.
3. Easy installation / removal
   The design allows it to be fitted or removed relatively simply: you remove the Akrapovič tailpipe set, then mount the dB reducer in its place. 
   This flexibility means you can switch between more aggressive sound (no reducer) and a quieter mode depending on use (e.g. street vs track).
4. Compatibility with existing Akrapovič systems
   It is designed to be compatible with various Akrapovič exhaust lines for the 991 GT3 / RS (Slip-On, Evolution, Race, etc.). 
   It also fits with or is compatible with the optional Akrapovič carbon-fibre diffuser for the GT3 (in terms of space and mounting)  
5. Maintains exhaust character / sound quality
   Although it attenuates overall noise somewhat, it is engineered to retain the “character” of the Akrapovič sound (i.e. tone, exhaust note) rather than making it dull or “muffled.”  

Caveats / Considerations:

• Limited attenuation
  The noise reduction is modest (2–3 dB). It won’t transform a loud exhaust into whisper quiet — it’s more of a fine-tuning / compliance aid.  
• Dynamic vs static noise
  The spec “dynamic sound levels” refers to the vehicle in motion, not stationary (idling or revving in place) noise levels.  
• Weight & packaging trade-off
  While titanium helps keep weight low, adding an extra piece (the dB reducer) does add some mass and complexity. In practice the weight addition is small, but it’s not zero.
• Does not replace muffler / exhaust tuning
  It is not a full muffler or performance exhaust in itself; it is a supplemental device. So improvements or losses in flow, back pressure, etc., depend on the rest of the exhaust system.
• Effect may vary by track / measurement method
  Because decibel measurements depend heavily on conditions, track layout, measurement distance, ambient environment, etc., the real-world noise reduction can vary.  
• Regulation / legality
  Depending on your local jurisdiction, modifications to exhaust systems need to pass noise / emissions inspections. Adding or removing components might affect roadworthiness approval. (This is a general caution — I didn’t find a source saying this particular part is illegal in your jurisdiction.)
