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.

Evolution Link Pipe Set (Titanium) was tested and developed together with Slip-On Line (Titanium).
The Evolution delivers more power, improves responsiveness, and keeps weight down. The uniquely designed muffler from the Slip-On with an added lightweight and exhaust flow–optimized link pipe set with bigger tubes fully represents the titanium Evolution. This performance exhaust has been created to produce a deep sound that transforms the Turbo into a real machine. This is especially the case after removing the point-welded block in the link pipe that prevents bypassing the muffler. The dual-mode system can be also used with the factory button to regulate the exhaust valves. Complete the look with a set of exquisite tailpipes in carbon fibre.
If the car is equipped with performance exhaust with electronic valve actuators than actuator set P-HF1006 is required and the Akrapovic sound kit P-HF1003 can not be used.
If the car is not equipped with performance exhaust and you want to use the Akrapovic sound kit than Akrapovic sound kit P-HF1003 together with Actuator set P-HF1006 has to be ordered.

Evolution Header Set (Titanium) was tested and developed together with Slip-On Race Line (Titanium) system.
This product is made using high-grade titanium, with the parts sandblasted and coated for durability. This new header set has a routing that has been designed to perfectly direct the gas flow. Showcasing the special manifold crossover pipes in the headers, cast in the Akrapovič in-house titanium foundry, this innovative design comes directly from race-proven exhaust systems, and this is the first time it has featured in an Akrapovič aftermarket car exhaust. This masterpiece of engineering is designed solely to optimize the performance of the Slip-On Race Line (Titanium) in the midrange. Many parts in the headers are cast in the in-house foundry, and the complete use of titanium results in a weight saving of 3.8 kg, which is 28% lighter than the stock equivalent.
Tuned quarter-length resonators in addition to the catalytic converters ensure the sound quality and the absence of any distortion or unwanted frequencies, creating a unique sound experience. The combination of an Akrapovič Slip-On Race Line (Titanium) and Evolution Header Set (Titanium), developed for use on closed-course competition circuits only, provides increases of 16.6 kW (22.6 hp) in power at 4,550 rpm and 35.2 Nm in torque at 4,500 rpm, when tested on the Akrapovič dyno against a Porsche 911 GT3 (992) with a standard stock exhaust.
When installing the Akrapovič Evolution Header Set (Titanium) on vehicles with particulate filters, remapping the ECU is mandatory to prevent potential “check engine light” warning signals. When installing the Akrapovič Evolution Header Set (Titanium) on vehicles without particulate filters, remapping the ECU is recommended.
This system fits also on vehicles equipped with Otto particulate filter (OPF).
