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.

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.

SOUND: If you're looking for a really aggressive exhaust note and you're not worried about waking up the neighbors, this is the system for you! This exhaust will deliver ripping sports car sound, at the cost of some interior drone. The Supercup is significantly louder than our Maxflo Exhaust, but If you want the best of both worlds, check out our TrackTec Valved Exhaust, which will be slightly louder than the Supercup with the valves open and just as civilized as our Maxflo system with the valves closed.

FEATURES:
• Fits all Porsche 981 Boxster/Cayman vehicles (2013-2016)

This system pairs SOUL Valved Exhaust with Long Tube Street Headers, delivering noticeable power gains, sharper throttle response, and a soundtrack that adapts to your driving mood—all without triggering a check engine light. With valves closed, the system offers a smooth, drone-free tone ideal for daily driving. Open the valves, and the flat-six unleashes its full roar through a straight-through flow path, exiting via exhaust tips in the style and finish of your choice. Built around large-diameter runners and high-flow catalytic converters, the headers maximize flow while enhancing that signature Porsche sound. Every system is backed by our industry-leading Lifetime Warranty, giving you confidence both on the street and at the track.
Package Includes:
• SOUL Performance Products 981 Cayman Valved Exhaust System
• SOUL Performance Products 981 Cayman Long Tube Street Headers
• Fits all Porsche 981 Boxster / Cayman models (2013–2016)
• Increased performance and sound with no check engine light
• Direct bolt-on installation with included instructions
• Multiple tip styles and finishes available – custom options too
• Covered by SOUL’s Lifetime Warranty for street and track use
DEVELOPMENT:
For the 981 platform, we engineered a system with properly sized 2” runners and optimized collectors to unlock maximum power from the 3.4L engine, while still delivering impressive gains on the 2.7L. We selected high-flow catalytic converters sized for both performance and durability—avoiding the compromises of smaller, cheaper alternatives. The result is a superior exhaust that delivers a broad spectrum of sound: valves open reveal a CUP car–inspired roar, while valves closed provide a refined, drone-free tone. Thanks to SOUL mufflers, even with aftermarket headers the exhaust remains composed and reserved when the valves are shut.
CONSTRUCTION:
Our headers are precision-engineered and crafted from T304L stainless steel for strength and performance. Featuring port-matched flanges, smooth-radius primary tubing, and optimized collectors, they deliver maximum exhaust flow and power gains. Each system is mandrel-bent, fitted with reinforced muffler casings for durability, and rigorously quality-checked before shipping to ensure the highest standards.
TIPS:
Choose from several different tip styles and finishes – from single wall 321 stainless tips to double wall chrome tips. Logo customization and custom tip colours are available by request. Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips!
BOLT ON AND GO:
Each exhaust is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY:
Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
