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

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

The JCR Inconel Race Exhaust Manifold & Titanium Silenced Link Pipe Assembly for the 982 Porsche 718 Cayman GT4 RS and Spyder RS is a high-performance, direct replacement system designed to maximize power, reduce weight, and deliver an exhilarating yet track-compliant exhaust note. Constructed from lightweight Inconel for the Race Manifolds and premium titanium for the Silenced Link Pipes, this assembly sheds significant weight over the OEM system while improving exhaust flow and throttle response. The integrated silenced sections lower sound levels by approximately 5-6dB, making it ideal for circuits with strict noise regulations without sacrificing performance. Engineered with precision for durability and modular fitment, this system enhances the flat-six tone, blending motorsport character with refined acoustics for both street and track use.

Direct Replacement / Modular Fitment

• JCR Titanium Link Pipes and Inconel Race Exhaust Manifolds are engineered as 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 additional fabrication or components are needed — owners can remove the factory parts and install the JCR system with the included hardware. Designed with modularity in mind, the Titanium Link Pipes allow for multiple configurations, as sections can be swapped out individually. Silenced, Non-Silenced, and Race-Silenced variants can be interchanged without requiring a full system replacement, enabling owners to easily adjust their exhaust setup to meet varying track noise requirements. Each kit arrives with all necessary hardware for a seamless installation.

Heat Management

• All JCR Link Pipe options are equipped with high-quality thermal protection as standard. The motorsport-grade heat shielding is specifically chosen to manage extreme temperatures and minimize radiant heat transfer to surrounding components. Extensive track testing by JCR, with and without shielding, demonstrated consistent reductions of 15-20°C in inner rear tire temperatures. This thermal efficiency not only enhances tire longevity but also provides a measurable performance advantage over unshielded systems.

Silenced

• This specific 718 GT4 RS / Spyder RS Link Pipe variant incorporates custom Titanium Silencers in the rear section, reducing sound levels by 5-6dB compared to the Non-Silenced Version. The straight-through silencer design preserves exhaust flow, ensuring performance remains uncompromised while meeting stricter noise limits.

Light Weight

• Constructed entirely from titanium for the Link Pipes and 100% Inconel for the Race Manifolds, the JCR system delivers dramatic weight savings over the OEM exhaust while simultaneously enhancing sound and performance. The use of lightweight motorsport-grade materials provides a tangible boost in handling and acceleration, making this an ideal upgrade for performance-driven owners seeking both power and efficiency.

Real World Performance Improvements

• Every component in the JCR Exhaust lineup is designed to increase horsepower and torque, with gains depending on the chosen configuration. On the 718 GT4 RS, JCR’s most aggressive free-flowing setup achieves up to 35 horsepower, along with sharper throttle response and improved mid-range torque. All systems undergo extensive track testing, including back-to-back 100-200kph acceleration runs, validating the real-world performance benefits that JCR exhaust upgrades deliver.
