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.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
