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

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

The JCR Inconel Race Exhaust Manifold & Titanium Race-Silenced Link Pipe Assembly for the 982 Porsche 718 Cayman GT4 RS and Spyder RS delivers a complete high-performance exhaust solution. Featuring lightweight Inconel Race Manifolds paired with Titanium Link Pipes equipped with 200-cell race silencers, this system optimizes exhaust flow for significant power and torque gains while maintaining track-compliant sound levels. The precision-engineered assembly reduces overall weight, enhances throttle response, and produces a sharper, more aggressive flat-six exhaust note. Designed as a direct bolt-on upgrade, it provides both exceptional performance and durability for demanding street or track use.

Direct Replacement / Modular Fitment

• JCR engineers its Titanium Link Pipes and Inconel Race Exhaust Manifolds as a complete direct replacement for the OEM OPF over-axle pipes and factory manifolds on the 718 GT4 RS and Spyder RS. No additional fabrication or extra components are required — factory parts can be removed and the JCR system installed using the included hardware. Designed with modularity in mind, the Titanium Link Pipes allow sections to be swapped individually, enabling quick changes between Silenced, Non-Silenced, and Race-Silenced variants without replacing the full system. Each kit is delivered with all necessary hardware for a straightforward installation.

Heat Management

• All JCR Link Pipe configurations include premium thermal protection as standard. Motorsport-grade heat shielding is selected to withstand extreme temperatures and reduce radiant heat transfer to nearby components. JCR’s extensive track testing, both with and without shielding, confirmed consistent inner rear tire temperature reductions of 15-20°C. This thermal efficiency improves tire longevity and provides a measurable performance advantage compared to unshielded systems.

Race-Silenced

• JCR’s Inconel Race-Silenced Link Pipes deliver the performance benefits of the standard Non-Silenced Titanium Link Pipes with the added advantage of reduced sound levels and integrated 200‑cell HJS race silencers. This configuration maintains horsepower and torque gains while offering only a modest increase in volume over the factory OPF pipes, keeping the system emissions‑compliant. Ideal for track use under strict noise regulations or for street cars requiring functional catalytic converters, this option is also compatible with the factory link pipes, as JCR’s 200‑cell race silencer is significantly less restrictive than the OEM assembly.

Light Weight

• Constructed from lightweight titanium for the Link Pipes and 100% Inconel for the Race Manifolds, the JCR system achieves substantial weight savings over the OEM exhaust while improving both sound and performance. The use of motorsport‑grade materials enhances handling and acceleration, making it a premium upgrade for performance enthusiasts seeking efficiency and power.

Real World Performance Improvements

• Every component in the JCR Exhaust lineup is developed to increase horsepower and torque, with results varying by configuration. On the 718 GT4 RS, JCR’s most aggressive free‑flowing setup delivers gains of up to 35 horsepower, along with improved mid‑range torque and sharper throttle response. All systems undergo rigorous track testing, including back‑to‑back 100-200kph acceleration trials, confirming the real‑world performance benefits of JCR’s exhaust solutions.
