Porsche 911 GT3 RS 992 | Akrapovic Performance Exhaust Installation

The Akrapovic Slip-On Race Line (Titanium) for the 992 GT3 platform has quickly become one of the most sought-after exhaust systems in the UK and Ireland. Seamlessly integrating with Porsche’s engineering, it delivers a far more engaging exhaust note, notable performance improvements, and significant weight savings—all without the need for a remap.

At PERON’s Performance Workshop, the installation of the Akrapovic Slip-On Race Line (Titanium) on the Porsche 992 GT3 RS was as seamless as we’ve come to expect from Akrapovic. Every Akrapovic system we handle is engineered with precision for superior fitment, ensuring a straightforward and efficient installation process. Akrapovic’s meticulous attention to detail allows each component to integrate effortlessly with the factory setup, aligning so perfectly it feels like an original part rather than an aftermarket upgrade.

This flawless integration, paired with the exceptional craftsmanship of the titanium exhaust system, transforms the 992 GT3 RS without compromise. The result is a perfect harmony of unmistakable sound, performance gains, and weight savings—all underpinned by the precision engineering and innovation that define the Akrapovic name.

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.

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.

Akrapovic Slip-On Race Line Adapter Set (SS) — P-CP034

The Slip-On Race Line Adapter Set (SS) is a mandatory component when installing the Akrapovič Slip-On Race Line (Titanium) and retaining the stock headers. Constructed from high-grade stainless steel, this adapter ensures optimal integration of the Slip-On Race Line system, delivering precise fitment and performance. Advanced insulation is incorporated to protect surrounding components from excess heat.

Topologically CFD-optimised and meticulously tested, the adapter ensures the Slip-On Race Line (Titanium) exhaust system delivers its characteristic performance and sound. For vehicles without particulate filters, plug inserts and nuts from the Akrapovič installation kit must be used to disable backpressure sensors.

Evolution Header Set (Titanium) E-PO/T/9

The Akrapovič Evolution Header Set (Titanium)  is a race-inspired upgrade engineered to elevate the performance and sound of the Porsche 911 GT3 RS and 911 S/T (992.1). Tested and developed alongside the Slip-On Race Line (Titanium), this header set optimises gas flow and enhances midrange power, making it the perfect addition for track-focused enthusiasts. Crafted entirely from high-grade titanium, it achieves significant weight savings and showcases innovative manifold crossover pipes cast in Akrapovič’s in-house titanium foundry. This groundbreaking design has been derived directly from Akrapovič motorsport applications.

Sound

The Evolution Header Set redefines the auditory experience of the Porsche 911 GT3 RS. Featuring tuned quarter-length resonators and catalytic converters, the system eliminates unwanted frequencies and distortion, delivering a unique, exhilarating sound. The result is a rich, high-frequency exhaust note with a +10.1 dB increase at 3,750 rpm, enhancing the car’s visceral driving experience while reflecting Akrapovič’s motorsport heritage.

Akrapovič dB Reducer (Titanium) — TP-PO991GT3/BOX

The Akrapovič dB Reducer (Titanium) is engineered for Porsche 911 GT3 and GT3 RS models, providing a solution for drivers looking to keep exhaust noise levels within approved limits during track days. Constructed from high-grade lightweight titanium, this precision-engineered accessory acts as an additional muffler, expanding exhaust gases further to effectively lower sound levels.

The dB reducer is easy to install, replacing the Akrapovič tailpipe set with minimal effort. Once in place, it reduces dynamic sound levels by approximately 2–3 decibels* without sacrificing the distinctive Akrapovič sound and performance. Its design seamlessly integrates with all Akrapovič exhaust systems for the Porsche 911 GT3 and GT3 RS, including:

CARGRAPHIC Exhaust Valve Controller — EXFLAPRCOEE3E
