JCR Inconel Valved Race Exhaust System for 918 Porsche 918 Spyder

The JCR Inconel Valved Race Exhaust System for the 918 Porsche 918 Spyder enhances one of Porsche’s most iconic models, addressing areas for improvement. By incorporating Inconel 625 and advanced motorsport heat shielding technology, JCR has successfully extracted additional power while introducing a remarkable new exhaust tone. This upgrade transforms the car’s character, especially when the roof is removed, amplifying both performance and sound.

Direct Replacement / Modular Fitment

The JCR Inconel Valved Race Exhaust System serves as a complete direct replacement for the OEM 918 Spyder rear silencer. No fabrication or additional parts are needed — simply remove the factory unit and install the JCR Inconel Valved Race Exhaust System to enjoy significant weight savings, increased power, and an extraordinary sound.

Heat Management

The JCR Inconel Valved Race Exhaust System for the 918 Spyder comes equipped with the highest quality thermal protection. The heat shielding used is sourced from the top levels of motorsport, designed to effectively manage temperatures and drastically reduce the impact of radiant heat on surrounding components.

Exotic Sound

The sound signature of the JCR Inconel Valved Race Exhaust System has been meticulously engineered to complement the 918 Spyder’s impressive capabilities. The previously flat and uninspiring exhaust note has been replaced with a striking V8 howl, now accompanied by a more substantial volume when desired. Through JCR’s calculated merge design, the 4.6L V8 in the 918 Spyder comes to life with a refined and exotic tone. This system maintains factory valve control, allowing for quiet cruising with valves closed, while providing the option for a significant volume increase when valves are open.

Light Weight

Thanks to the choice of materials and construction, JCR was able to achieve all performance goals while reducing the weight of the OEM system by over 50%. This results in a net weight savings of more than 7.81kg (17.2lbs) from the rear of the vehicle, benefiting the car’s overall performance by reducing mass at a high, central location.

Performance Increase

Each component of the JCR exhaust line is engineered to deliver an increase in horsepower and torque, with gains varying based on the specific combination of parts installed.

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.
