JCR Titanium Non-Valved Race Exhaust System for 991.2 Porsche 911 GT3 RS (with OPF) / Speedster

The JCR Titanium Non-Valved Race Exhaust System for the 991.2 Porsche 911 GT3 RS (with OPF) and Speedster delivers maximum performance and a raw motorsport experience, available in either Silenced or Non-Silenced configurations to suit individual sound preferences. Crafted entirely from lightweight titanium, this system offers significant weight savings, improved exhaust flow, and enhanced throttle response. Buyers can choose from a range of premium exhaust tip options — including Titanium Megaphone, Titanium Straight, Titanium Superlight Megaphone, Inconel Rolled, and Titanium Silenced Tips — with each available in Raw (titanium), Polished (inconel), or Black Coated finishes, excluding Titanium Silenced Tips. OEM tips are also compatible, provided they feature the required 3-bolt flange design, ensuring a perfect fit and finish for both performance-focused track builds and refined street applications.

Light Weight

Due to its 100% titanium construction, the JCR Titanium Silenced Race Exhaust System delivers exceptional weight savings over the OEM steel exhaust. Reducing weight is always beneficial, but removing mass rearward of the 911’s rear axle provides significant improvements in handling balance. This upgrade offers a dual advantage, saving just over 12 kg from the rear.

The Design

Through extensive testing and development, JCR has refined multiple aspects of the exhaust system’s design to precisely tune and enhance both the tone and pitch of the Race Exhaust System’s sound and performance. The system incorporates fabricated bends that transition from the large internal diameter directly off the OPF, tapering down to 70mm pipework to achieve optimal back pressure — maintaining low-end torque while allowing unrestricted airflow to the 9000rpm redline. The exhaust flow then merges into a collector designed to create a scavenging effect while targeting and reducing unwanted drone frequencies, before exiting through twin 70mm pipes into the factory 991 GT-style 3-bolt flange. This allows customers to select any tip compatible with the OEM-style flange.

Valve Delete

The JCR Titanium Non-Silenced and Silenced Race Exhaust Systems remove the factory valve-switching function for a pure, unrestricted driving experience. Since all 992 GT3 / RS models feature electronic valve control, eliminating it without proper measures can lead to poor running and check engine lights. To address this, all JCR Non-Valved Race Exhaust Systems are supplied with electronic valve delete modules, ensuring flawless operation. Once the JCR Valve Delete Kit is installed, the car runs exactly as it would from the factory.

Performance Increase

Every component within the JCR Titanium Exhaust range is engineered to deliver measurable gains in both horsepower and torque, with the exact improvement varying based on the combination of parts used.

RSR Sound

For enthusiasts familiar with the sound of the 2018 GTE 911 RSR, JCR sought to replicate that unmistakable race-bred tone with the Titanium Race Exhaust System. This acoustic signature, first achieved on the non-OPF system, has been carried over to the latest OPF Titanium Race Exhaust System. The Silenced Race Exhaust variant integrates bespoke titanium silencers into the standard Race Exhaust design, reducing overall dB levels while retaining its signature character.

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.
