Will the Fabspeed RENNKRAFT Modular Headers fit my 992 GT3 or GT3 RS?

They fit the 992.1 Porsche 911 GT3 from 2022 through 2024 and the 992.1 GT3 RS from 2023 through 2024. Fabspeed builds a separate version for 992.2 cars from 2025, so check your model year first. The headers were designed from 3D laser scans of the factory parts, so fitment is exact with no cutting or welding.

What does the modular design actually do?

A US patented quick-release V-band connector sits between the headers and the mid-section, so you can run German HJS 200 cell Euro 6 catalysts for road use and change to QUICKTRACK competition pipes for closed-course events. It takes minutes with hand tools. One set of headers covers both uses instead of two separate systems.

How much power does it make?

Fabspeed's dyno work showed 16 whp and 20 ft-lbs with the Sport Cats and 19 whp and 26 ft-lbs with the competition pipes, both with no tune. Peak output went from a 452 whp baseline to 461 whp with the Sport Cats and 468 whp with the competition pipes. No ECU tune is required for either configuration.

Will it throw a check engine light?

Not in the Sport Cats configuration on a car without a GPF, which Fabspeed guarantees. European GPF-equipped cars are a different matter and will set a light unless a simulator or tune is used, which is why those cars should be treated as closed-course only. The competition pipe configuration is for track use.

Do I need a new exhaust system as well?

No. The headers work with the factory muffler and do not introduce drone, so this can be the only change you make. They also pair with any of Fabspeed's cat-back systems for this chassis if you want the full build, and the complete front-to-back version is sold as the RENNKRAFT Modular GTLM Exhaust Package.

Why the HJS catalysts specifically?

They are German imported EMITEC HJS HD tri-metallic units, 200 cell and Euro 6 homologated, and Fabspeed developed this system in direct collaboration with HJS in Germany. Fabspeed specified the largest catalyst that physically fits the factory location, which is what lets the system flow while keeping proper emissions equipment on a road car.

Description

Fabspeed RENNKRAFT Modular Headers with HJS Cats for 992.1 Porsche 911 GT3 & GT3 RS

The Fabspeed RENNKRAFT Modular Headers answer a question every 992 GT3 owner with a track habit eventually runs into: how do you build one car that works properly on a Tuesday commute and on a Saturday at a sound-limited circuit, without owning two exhausts. RENNKRAFT translates as race power, and the answer is a US patented quick-release V-band connector sitting between the headers and the mid-section. German imported EMITEC HJS 200 cell Euro 6 homologated catalysts go in for the street. QUICKTRACK competition pipes go in for closed-course work. The change takes minutes in your own garage. Everything ahead of that joint is CNC mandrel-bent T304L stainless with lost wax investment cast inlet flanges and F1 style triangular merge collectors, designed from 3D laser scans of the factory headers, six pounds lighter than what came off the car.

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.
