JCR Inconel Race Exhaust Manifold & Titanium Non-Silenced Link Pipe Assembly for 982 Porsche 718 Cayman GT4 RS / Spyder RS

JCR Inconel Race Exhaust Manifold & Titanium Non-Silenced Link Pipe Assembly for 982 Porsche 718 Cayman GT4 RS / Spyder RS

The JCR Inconel Race Exhaust Manifold & Titanium Non-Silenced Link Pipe Assembly for the 982 Porsche 718 Cayman GT4 RS and Spyder RS is engineered for maximum performance and sound. Crafted from ultra-lightweight Inconel Manifolds paired with titanium non-silenced Link Pipes, this system removes factory restrictions to deliver exceptional exhaust flow, sharper throttle response, and substantial weight savings compared to OEM components. The non-silenced configuration produces an aggressive, race-inspired tone that transforms the 4.0L flat-six into a high-revving howl, making it ideal for track use and for drivers seeking the rawest sound experience. Designed for direct bolt-on installation with motorsport-grade precision, this JCR assembly offers uncompromising performance, durability, and sound in a complete package.

Direct Replacement / Modular Fitment

• JCR Titanium Link Pipes and Inconel Race Exhaust Manifolds are a complete direct replacement for the OEM OPF pipes (over-axle / link pipes) and factory manifolds on the 718 GT4 RS and Spyder RS. No fabrication or additional parts are required — simply remove the factory components and install the JCR system using the supplied hardware. Thanks to a modular design, JCR’s Titanium Link Pipes can be configured to suit various setups by swapping out specific sections, which are available separately. Silenced, Non-Silenced, and Race-Silenced variants can be interchanged without the need to purchase a full new system, allowing owners to adapt their exhaust based on track noise regulations. Each kit includes all necessary hardware for a straightforward, hassle-free installation.

Heat Management

• All JCR Link Pipe configurations come equipped with premium thermal protection as standard. The selected heat shielding is sourced from the highest levels of motorsport to effectively manage temperatures and reduce radiant heat affecting nearby components. JCR conducted thousands of miles of track testing with and without heat shielding and consistently recorded reductions of 15-20°C in inner rear tire temperatures. These real-world performance benefits result in increased tire longevity and a measurable advantage over systems lacking thermal insulation.

Non-Silenced

• This version of the JCR 718 GT4 RS / Spyder RS Link Pipes is the fully Non-Silenced variant. It represents the lightest and loudest configuration in the Titanium Link Pipe lineup, offering the most aggressive sound signature available.

Light Weight

• With full Titanium construction for the Link Pipes and 100% Inconel construction for the Race Manifolds, this JCR system delivers substantial weight savings over the OEM exhaust while enhancing both power and sound. The use of lightweight motorsport-grade materials ensures a noticeable improvement in overall performance without compromise. This setup is the ultimate win-win upgrade for performance-focused owners.

Real World Performance Improvements

• Every component in the JCR Exhaust range is developed to increase horsepower and torque, with gains dependent on the combination of parts installed. On the 718 GT4 RS, JCR’s most extreme free-flowing configuration yields up to 35hp, along with sharper throttle response and stronger mid-range torque. All development has been guided by rigorous track testing, including before-and-after acceleration measurements from 100-200kph, confirming the real-world effectiveness and performance gains experienced by owners who upgrade to JCR systems.
