Fabspeed RENNKRAFT Modular Headers for 982 Porsche 718 Cayman GT4 RS

Fabspeed’s RENNKRAFT Modular Headers for the 982 Porsche 718 Cayman GT4 RS represent the ultimate long-tube solution, distilled from over 30 years of Porsche engineering experience. By relocating the primary catalytic converter behind the rear axle, Fabspeed created true long-tube primaries and replaced the restrictive 700 cell ceramic cat with an HJS 200 cell tri-metallic sport catalyst for drastically improved power and a sharper, motorsport sound without triggering a CEL. The patented RENNKRAFT quick-release v-band interface lets owners swap between catted and cat-bypass sections in minutes for street or track use. A new bi-layer thermal shield rated to 2400F/1300C dramatically cuts radiant heat to nearby components like the rear shock body, while the system’s OEM-grade fit and modularity deliver a durable, future-proof upgrade for the GT4 RS.

Sound

Fabspeed’s headers with sport catalysts let the GT3-derived GT4 RS powerplant fully breathe, turning performance and character up to eleven. With the factory muffler retained, the car delivers an aggressive, deeper tone, and volume can be dialed back by switching off PSE. Paired with Fabspeed’s Valvetronic X-Pipe, the system produces a ripping, high-pitched soundtrack while preserving on-demand quiet via the factory PSE button.

Power

Fabspeed’s system is the most powerful header upgrade available for the GT4 RS, delivering max gains of +48whp and +54ft-lb at 4700 rpm. Equivalent to roughly +53hp at the crank, peak power rises from 456 to 490whp, producing a dramatic, clearly felt increase in acceleration and midrange punch.

Frequently Asked Questions

Will the Fabspeed RENNKRAFT Modular Headers fit my GT4 RS? They are engineered for the 982 Porsche 718 Cayman GT4 RS from 2022 to 2025 with the 4.0-liter flat-six. Fabspeed also lists the system for the 718 Spyder RS, so confirm fitment for your specific model before ordering.
How much power do they add? On Fabspeed’s development car in the Sport Cats configuration with the OEM muffler, the Fabspeed RENNKRAFT Modular Headers lifted output from 456 to 490 wheel horsepower, with a maximum gain of 48 wheel horsepower and 54 lb-ft at 4,700 rpm, roughly 53 horsepower at the crank, and saved about five pounds. Results vary with configuration and conditions.
What configurations are available? Two: Sport Cats, which uses 200-cell HJS sport catalysts and is engineered to run without a check engine light, and Sport Cats with Competition Pipes, which is intended for race or track use only and may trigger a check engine light.
Will it keep the catalytic converters and avoid a check engine light? The Sport Cats configuration uses high-flow 200-cell HJS sport catalysts and is engineered to run with no check engine light. The Competition Pipes configuration is for closed-course use and may set one, so choose based on how the car is used.
Does it work with the Valvetronic exhaust? Yes. The headers are designed to pair with the Fabspeed Valvetronic X-Pipe cat-back for the complete GT4 RS exhaust system.
Is it emissions legal or CARB approved? No. This system is not CARB approved and is not for sale or use in California or other states that require CARB certification, and the Competition Pipes configuration is for race or track use only. Check your local and state regulations before ordering or installing.

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.
