JCR Titanium Non-Valved Race Exhaust System for 982 Porsche 718 Cayman GT4 RS / Spyder RS

JCR Titanium Non-Valved Race Exhaust System for 982 Porsche 718 Cayman GT4 RS / Spyder RS

The JCR Titanium Non-Valved Race Exhaust System for the 982 Porsche 718 Cayman GT4 RS and Spyder RS is designed to unlock the full potential of your car’s performance while giving you the flexibility to choose the exhaust note that fits your style. Available in both Silenced and Non-Silenced versions, this system ensures you get the best of both worlds — whether you’re looking for a refined tone with the silenced version or an aggressive, unrestricted exhaust sound with the non-silenced option. You can also personalize your setup with Titanium Megaphone Tips or Titanium Weissach Tips, available in Polished, Raw (weissach only), or Black Coated finishes. It’s the perfect choice for anyone wanting to enhance both the performance and appearance of their 718 Cayman GT4 RS or Spyder RS.

Direct Replacement / Modular Fitment

• The JCR Titanium Race Exhaust System is a complete direct replacement for the OEM 718 GT4 RS rear silencer assembly. No fabrication is required — simply remove the factory rear silencer and replace it with the JCR Race Exhaust System using the factory mounting points. The system includes Titanium Megaphone Tips as standard, with additional options available. The tips are secured with motorsport-grade v-band clamps, ensuring perfect alignment every time and allowing for quick changes at the track. This includes the option to install Titanium Silenced Tips, which reduce sound levels by an additional 5-6dB, ensuring that owners using their cars on track will not have issues with excessive noise during strict track events.

Light Weight

• Thanks to its construction and material choice, the JCR Titanium Race Exhaust System achieves all performance goals while reducing the weight of the OEM system by over 50%. This modification provides a clear performance benefit while shedding significant weight.

Performance Increase

• Every component in the JCR Titanium Exhaust line is guaranteed to improve horsepower and torque, with results varying depending on the specific combination of parts. For the direct replacement rear silencer, peak gains are an impressive 11 horsepower and 5 lb-ft of torque, with improvements across the full RPM range.

Non-Valved, Modular Design

• The Non-Valved Race Exhaust System design deletes the factory valve function, offering unrestricted sound across the entire RPM range. The JCR Titanium Race Exhaust System is designed for modular and quick fitment, allowing either Silenced or Non-Silenced sections to be easily swapped. This modularity enables the system to be quieted when needed or fully opened up for non-silenced track events.

JCR Tips

• During the development of the 718 GT4 RS exhaust system, it became clear that the factory Titanium Weissach tips could not be retained if maximum power gains were to be achieved, as their restrictive internal diameter limited exhaust flow. This led JCR to develop their own Titanium Tips, inspired by the factory tips on the 718 GT4 RS with the Weissach package. JCR also offers a more conventional Titanium Megaphone design, and both the Titanium Megaphone and Titanium Weissach Tips are available with or without black coatings.

GT3 Style Sound

• The sound signature of the JCR Titanium Race Exhaust System has been engineered to closely resemble JCR’s highly popular GT3 product line. The exhaust note is transformed from a flat and dull sound to a rich, high-pitched flat-six tone, with an increased volume upon request. Using the same merge design as JCR’s existing Race Exhaust System products, the 4.0L GT3-derived engine now howls as expected at 9000rpm.
