Akrapovic Exhaust System for Porsche 911 GT3RS (992)

Developed solely for the 911 GT3 (992), this high-grade lightweight titanium system is sandblasted and coated for durability. The completely new design includes twin tailpipes, with the outer shell coated and the inner sleeve featuring six imprints to match the six-cylinder engine, with an engraved Akrapovic logo to complete the visual effect. The housing of the exhaust valves – which have been tailored perfectly to the gas flow to produce a smooth, rich tone at normal cruising and a sporty sound experience at higher revs – and the collectors in the muffler are cast in the Akrapovic in-house foundry. When combining the Slip-On Race Line (Titanium) with the Slip-On Race Line Adapter (SS), the weight is decreased by 20.7% (3.5 kg) against the standard system and performance sees an increase of 6.5 kW (8.8 hp) in power at 2,900 rpm and a torque rise of 24.1 Nm at 2,400 rpm when tested on the Akrapovic dyno against a Porsche 911 GT3 (992) with a standard stock exhaust. This system is intended for use on closed-course competition circuits only because it is a racetrack-oriented part. No remapping of the ECU is required.

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).

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.

This product is designed for mandatory use with the Akrapovic Slip-On Race Line (Titanium) if the stock headers are retained. Constructed from high-grade stainless steel, this set utilizes special insulation to prevent any excess heat from affecting other parts. The Slip-On Race Line Adapter’s design ensures perfect performance and sound from the Slip-On Race Line (Titanium) exhaust system because the gas flow has been topologically CFD optimized and meticulously tested on the vehicle.

For vehicles without particulate filters, plug inserts and plug nuts from the Akrapovic installation kit must be used to disable the backpressure sensors.

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 Akrapovic 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 Akrapovic 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 Akrapovic 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 Akrapovic dyno against a Porsche 911 GT3 (992) with a standard stock exhaust.

When installing the Akrapovic 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 Akrapovic 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).

This product does not fit on standard 911 GT3 (992) version.

Designed and constructed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovic 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 Akrapovic tailpipe set and then mounting the dB reducer in place. After installation, the Akrapovic dB reducer (Titanium) reduces dynamic sound levels* by approximately two or three decibels** while still retaining the unique Akrapovic sound and character. It is designed to fit and reduce the measured dynamic sound levels of all Akrapovic 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 Akrapovic dB reducer (Titanium) is also totally compatible with the optional Akrapovic carbon-fibre diffuser, which is available for the Porsche 911 GT3 (991).

The Akrapovic 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.
