Elevate your Porsche with the Akrapovič Slip-On Race Line Exhaust System, expertly designed to integrate seamlessly with the original system of your Porsche 911. This system, constructed from high-grade titanium and highlighted by dual round tailpipes, boosts your car’s power and reduces its weight while delivering the distinctive, sporty Akrapovič sound that resonates with racing heritage.

Key Features:

High-Grade Titanium Construction: Ensures durability and a significant reduction in overall weight.
Dual Round Tailpipes: Provide an aggressive aesthetic and contribute to the enhanced exhaust flow.
Optional Carbon-Fibre Diffuser: Available to increase visual appeal and aerodynamic efficiency. Note: Specific tail pipe sets are required when combining with the carbon fibre diffuser.
Modular Design: Allows for easy integration with optional link pipe sets and full Akrapovič exhaust systems, including the Evolution Race Header Set with or without valves. This modularity provides flexibility in enhancing sound and performance characteristics to suit your preferences.

With its exceptional workmanship and cutting-edge technology, the Akrapovič Slip-On Race Line exhaust system not only amplifies your vehicle's performance but also its presence on the road or track, ensuring it stands out with a powerful racing growl that matches its enhanced capabilities.

911 GT3 RS (991.2) - OPF/GPF / 911 Speedster - OPF/GPF:

This Slip-On Race system (S-PO/TI/8) must be upgraded into a full Akrapovič Evolution Race Line exhaust system by combining it with the Evolution Header Set (E-PO/T/6) with side mufflers and valves, which is designed to supplement the performance at higher revs. With complex parts cast in Akrapovič’s own titanium foundry, the expertise used in this system, and the coating finish, the system demonstrates the highest standard of workmanship and technology. Incorporating 100 cpsi sports catalytic convertors in the exhaust manifold and side mufflers, the Evolution Race Line utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver a complete workout for the senses. The system offers a near-perfect power curve, along with an altered torque distribution, all designed to continually deliver performance as the revs rise. The use of lightweight materials results in big weight savings, and the addition of the Evolution Race Line will have the car performing like a true cup racer, with a powerful racing sound that resonates with every push of the accelerator pedal, producing a deep, pure racing growl to match the performance.

When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.

Mandatory Parts:

• Evolution Header Set (E-PO/T/6/1)
• Tail pipe set TP-T/S/19. When combining the slip-on system with optional carbon fibre diffuser DI-PO/CA/7/G, you must use tail pipe set TP-T/S/17.
• An additional original Porsche stock bracket (Porsche p/n: 99111147391) is required for mounting the Akrapovič exhaust system. Please read the instructions carefully before the start of the installation.

911 GT3 RS (991.2)

•  The Slip-On Race system can be optionally combined with Link Pipe Set (Titanium) that retains stock headers and removes stock side mufflers, or it can be upgraded into a full Akrapovič exhaust system, either with combining it with Evolution Race Header Set without valves or Evolution Header Set with side mufflers and valves.
