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.

Akrapovic Evolution Header Set (Titanium). Porsche 911 GT3 / GT3 Touring (992) 2021-24
- Porsche 992 GT3 4.0L / 992 S/T 4.0L
Fits:
Porsche 911 GT3 (992.1) 2021 - 2024
Porsche 911 GT3 Touring (992.1) 2021 - 2024
* This product does not fit on RS version.
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).
NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

- Porsche 992 GT3 4.0L / 992 S/T 4.0L
- Porsche 992 GT3 RS 4.0L
Fits:
Porsche 911 GT3 (992.1) 2021 - 2024

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 911 GT3, GT3 Touring, GT3 RS and S/T 992.1. Crafted entirely from lightweight, high-grade titanium, this system is designed to enhance every aspect of the driving experience—from sound and performance to weight savings and aesthetics. More than just an exhaust, it’s the finishing touch the 992 deserves and how it should have come from the factory. With motorsport-inspired engineering and a focus on lightweight performance, this system sets a new benchmark for track-focused upgrades.
Sound
The Akrapovič Slip-On Race Line delivers a +4.1 dB increase, enhancing the natural tone of Porsche’s iconic flat-six engine. It produces a smooth, rich sound at cruising speeds and transitions to a sportier, more aggressive note at higher revs. The housing of the exhaust valves – tailored to optimise gas flow – and the collectors in the muffler are cast in Akrapovič’s in-house foundry for precision and durability. This system ensures a dynamic and engaging exhaust note while eliminating intrusive droning, making it ideal for driving in all conditions.
Performance
The Akrapovič system for the 992 is engineered to maximise performance on the track by improving exhaust flow and reducing back pressure, all while achieving significant weight savings. This freer-flowing titanium design sharpens throttle response and enhances acceleration for a more engaging driving experience. No ECU remap is required when stock headers are retained and the Adapter Set is installed. However, for those upgrading to a full Evolution Line system with the Akrapovič Header Set, remapping the ECU is recommended to avoid Check Engine warning signals and ensure optimal performance.
Porsche 911 GT3 / GT3 Touring (992)
• Adapter Set (SS) with Stock Headers (P-CP034): +8.8 hp at 2,900 rpm, +17.8 ft-lb at 2,400 rpm, and 3.5 kg (20.7%) weight savings.
• Evolution Header Set (Titanium) (E-PO/T/7): +22.6 hp at 4,550 rpm, +26.0 ft-lb at 4,500 rpm, and an additional 3.8 kg weight reduction (28% lighter than stock headers).
Porsche 911 GT3 RS / S/T (992)
• Adapter Set (SS) with Stock Headers (P-CP034): +14.1 hp at 2,600 rpm, +28.1 ft-lb at 2,600 rpm, and 3.5 kg (20.7%) weight savings.
• Evolution Header Set (Titanium) (E-PO/T/9): +19.6 hp at 2,600 rpm, +36.4 ft-lb at 2,600 rpm, and an additional 3.8 kg weight reduction (28% lighter than stock headers).
These options give owners the flexibility to choose the setup that best matches their performance needs, whether retaining the factory headers for simplicity or upgrading to a full titanium system for maximum gains.
Design
Meticulously designed to match the Porsche 911’s iconic styling, the Slip-On Race Line combines functionality and aesthetics. The twin titanium tailpipes feature a sandblasted and coated finish, with six imprints on the inner sleeve to mirror the engine’s six cylinders. Akrapovič’s attention to detail extends to the in-house cast valve housings and muffler collectors, ensuring exceptional durability and performance. The lightweight construction is engineered to fit seamlessly within the car’s underbody, delivering both form and function for the ultimate track experience. Modern exhaust regulations often restrict the true character of performance cars, but Akrapovič’s Slip-On Race Line (Titanium) brings the Porsche 911 GT3 and GT3 RS to life. With its lightweight titanium construction, thrilling sound, and race-proven performance, this system is the ultimate upgrade for track enthusiasts. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
This system fits also on vehicles equipped with Otto particulate filter (OPF).
If fitted with the stock headers in place, the system requires the P-CP034 Slip-On Race Line Adapter (SS) as a mandatory part for installation.
For clients intending to install the complete exhaust system, the E-PO/T/7 Evolution Header Set (Titanium) must be ordered separately.
Please notice that you may need to order new original Porsche V-clamps that fix the link pipes onto the headers, in case they are damaged during the removal of the stock exhaust.
Please note: that the product shown in the pictures may present the Slip-On Race Line (Titanium) in combination with the Evolution Header Set (Titanium) or in combination with the Slip-On Race Line Adapter (SS).
