JCR Titanium Valved Race Exhaust System for 982 Porsche 718 Cayman GT4 and GTS 4.0 / 718 Boxster GTS 4.0 and Spyder

JCR Titanium Valved Race Exhaust System for 982 Porsche 718 Cayman GT4 and GTS 4.0 / 718 Boxster GTS 4.0 and Spyder

The JCR Titanium Valved Race Exhaust System for the 982 Porsche 718 Cayman GT4, GTS 4.0, Boxster GTS 4.0, and Spyder is a high-performance exhaust upgrade available in both Silenced and Non-Silenced versions, offering a tailored sound and driving experience. Both versions are crafted from 100% titanium, with the silenced version incorporating integrated silencers that reduce noise at low speeds while still allowing for a more aggressive exhaust note when the valves are open. The non-silenced version, on the other hand, provides a straight-through exhaust path, delivering a louder and more pronounced exhaust tone. Both systems retain factory valve control, ensuring no check engine lights and maintaining emissions compliance. They offer a significant weight reduction of over 10kg (22lbs) compared to the OEM rear silencer, improving vehicle dynamics. Additionally, both versions deliver a performance boost of 15hp and 6Nm in torque. Easy to install with no fabrication required, the JCR Titanium Valved Race Exhaust System is the ideal upgrade for enthusiasts seeking to enhance both sound and performance.

Direct Replacement / Modular Fitment

• The JCR Titanium Valved Race Exhaust System is a direct replacement for the OEM 718 GT4 and Spyder rear silencer assembly. No fabrication is required — simply remove the factory rear silencer and install the JCR Valved Race Exhaust System. The system includes titanium tips fixed on V-band clamps, ensuring perfect alignment every time. This also allows for quick changes at the track to the optional JCR Titanium Silenced Tips, which reduce sound levels by 6-7dB, making this system ideal for track use where strict noise regulations are enforced.

Light Weight

• Thanks to the construction and material choices, JCR has not only achieved all performance goals but also reduced the weight of the OEM system by over 60%. This results in a significant weight saving of over 10kg (22.04lbs) from the rear of the car, making it a truly beneficial modification.

Performance Increase

• Every component in the JCR Titanium Exhaust line is engineered to improve horsepower and torque, with results varying depending on the specific combination of parts.

Silenced

• The Silenced version of the 718 GT4 / Spyder / GTS 4.0 Valved Race Exhaust System includes silencers in the exhaust route when the valves are closed, creating a larger difference in volume between the valves open and closed positions. This results in a slightly quieter sound than the Non-Silenced version, as gases pass through the silenced section when the valves are open. This version is recommended for those who prefer a more OEM-like volume at low speeds or plan to replace more of the factory exhaust system with JCR components.

Non-Silenced

• The Non-Silenced version of the 718 GT4 / Spyder / GTS 4.0 Valved Race Exhaust System features small diameter straight pipes in the valves closed exhaust route, which leads to a smaller volume delta between valves open and closed. This version produces a louder, more aggressive sound, as the gases pass through non-silenced sections when the valves are open. It is recommended for those looking for a more aggressive exhaust note.

GT3 Style Sound

• The sound signature of the JCR Titanium Valved Race Exhaust System has been engineered to closely match the popular GT3 product line. The previously flat and dull exhaust note is replaced with a beautiful flat-six tone, accompanied by a more substantial volume when desired. Using the same merge design as JCR’s Race Exhaust System products, the 4.0L flat-six engine in the 718 GT4 and Spyder is brought to life with an exotic, high-quality tone that enthusiasts have been craving. The system retains factory valve control, ensuring no drone during cruising and the ability to increase volume when the valves are open.
