JCR Inconel Downpipe for 992.2 Porsche 911 Carrera GTS and 4 GTS / Targa 4 GTS

The JCR Inconel Downpipe for the 992.2 Porsche 911 Carrera GTS, Carrera 4 GTS, and Targa 4 GTS is a direct replacement for the OEM downpipe, designed to significantly reduce weight and deliver substantial gains in power and torque. Crafted from 100% Inconel 625, it is a high-performance, future-proofed component. The product is available in two options — as a Race Silenced version, which utilizes a high-flow HJS 200-cell core to replace the factory components, or as a Non-Silenced version, for maximum performance and sound. Both versions offer improved throttle response, transient boost response, and are designed using 3D printing technology for optimal gas flow. The Silenced version saves over 6kg, while the Non-Silenced version saves over 7kg.

Version

Race Silenced: The JCR Race Silenced section utilizes a single, high-flow HJS 200-cell core race silencer. As a result, flow is greatly increased, and improved performance follows. For cars without OPF monitoring, JCR’s race silencers in most cases will not cause any CEL and do not require any tuning. In certain instances, it’s still possible for a CEL to occur. This tends to happen if the car has poor fuel quality in the tank or excess load is applied when the engine and exhaust system are not up to full operating temperature.
Non-Silenced: With the JCR Non-Silenced section, the factory restrictive assembly is removed for maximum performance and sound. Rather than simply removing the silencer from their race silenced products, JCR created an entirely new profile to correctly control the gasses from the turbo flange down to the main flow path to optimize performance.

Light Weight

Through the use of lightweight materials and clever design, JCR has managed to significantly reduce the overall weight of the factory 992.2 Carrera GTS exhaust components. While removing weight offers great benefits in any performance vehicle, the gains are amplified on this platform, as reducing the rear-biased weight distribution helps to improve overall balance and handling. With only their Race Silenced version installed, JCR saves a total of 6.18kg (13.62lbs) from the weight of the vehicle, which represents a significant 49.83% reduction. With only their Non-Silenced version installed, JCR saves a total of 7.71kg (16.99lbs) from the weight of the vehicle, which represents a significant 62.2% reduction.

Direct Replacement

All of the JCR 992.2 Carrera GTS exhaust components are a direct replacement for their OEM equivalents, with a guaranteed perfect fit every time. No further work is required during installation beyond removing the OEM part and replacing it with its JCR equivalent and any supplied hardware.

3D Printed Components

3D printing or DMLS / SLM / DMP as it is referred to, is a technology that allows complex shapes that would have usually been reserved for casting or multi-axis machining to be created as one-off parts without large investments in tooling. This technology is particularly helpful in applications where the required geometry of a part might be outside the normal scope of other available manufacturing techniques. While this isn’t the first use of 3D Printed parts in JCR exhaust systems, their new 992.2 GTS Downpipes certainly feature this production method more extensively to ensure the best possible flow characteristics and performance.

Power Increase

Every component of the JCR 992.2 GTS Exhaust line is guaranteed to improve horsepower and torque, with varying results dependent on the combination of parts. Porsche quotes factory HP and TQ numbers at 533.6hp and 570Nm. JCR found the stock car to be making close to the quoted hp numbers but significantly more torque. Stock figures as tested on the day were 543hp and 636.1Nm. With their Race Silenced version installed, the car made a total of 580hp and 667.9Nm, which represents a 37hp and 31.8Nm gain versus OEM. The peak number delta only tells part of the story. With their Non-Silenced version installed, the car made a total of 585hp and 676.2Nm, which represents a 42hp and 40.1Nm gain versus OEM.

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.
