Information
RENNKRAFT™ Modular street and racing headers with HJS catalytic converters.
These modular headers are the perfect solution for any street driven 4.0 liter Cayman or Boxster. Our modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass "straight pipes" for track use. Rennkraft, translated from German is "race power". These unique headers offer true street and racetrack functionality in an innovative precision engineered package.
SOUND:
Many have complained about the lack of sound with the new 718 4.0ltr cars, these high flowing headers completely solve that issue. Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. With the cat bypass pipes installed, you're in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn't overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car. With the stock muffler in place, there is no drone what-so-ever, even with our Over Axle GPF Delete Pipes also installed.
POWER:
After extensive dyno development we found that mid length headers made the most power across the entire power band. With no tune, compared to a stock car we gained 31 whp and 19 ft/lbs of TQ at 7400 RPM with Sport Cats and 33 whp and 24 ft/lbs of TQ at 7200 RPM with Cat Bypass Pipes installed. That's a gain of 33 HP and 36 HP, respectively, at the crank! Peak horsepower also increased from our baseline of 383 whp to 405 whp with our HJS Sport Cats and 409 whp with Cat Bypass Pipes. See our dyno graph above for more details.
FEATURES:
• Fits all Porsche 4.0L Cayman/Boxster GT4/GTS/Spyder vehicles 2020+
• Impressive dyno proven power gains of 31 whp and 19 ft/lbs of TQ with the Sport Cats and 33 whp and 24 ft/lbs of TQ with Cat Bypass installed
• Save 2 lbs / 0.9 KGs with Sport Cats and 7 lbs / 3.2 KGs with Cat Bypass compared to the factory headers
• Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
• Switching to cat-bypass for track events prevents catalytic converter degradation during all out competition racing abuse
• F1 style high velocity merge collectors
• Designed from 3D scans of the OEM headers so we can achieve perfect bolt-on fitment
• We use German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for the best performance and reliability
• We use the largest catalytic converters that will fit in the factory location for maximum flow
• Flows 93% of a 2.5 in straight pipe
• Will NOT cause a CEL (Check engine light), NO P420 or P430 codes, when Sport Cats are installed
• No ECU tune required
• NOT EPA or CARB Certified and not be used on street driven vehicles
• Will fit with any brand of aftermarket exhaust system designed to work with the factory headers
• Built 100% in house at Fabspeed Motorsport USA in Fort Washington, PA
• These are the very finest headers for the 718 4.0 liter cars and where developed in collaboration with HJS Emissions Technology
• 25+ years of air-cooled and water-cooled Porsche experience went into our design for these hand-crafted headers
• Constructed from CNC mandrel-bent T304L stainless steel
• Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty.
Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
Sport Catalytic Converter (STREET) - This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.
Cat Bypass (RACE) - This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. We suggest pairing this product with racing software to prevent fault codes and check engine lights. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.
Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.
NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

Evolution header set (Titanium).
Fits:
Porsche 911 (991.2) GT3 RS 2020
Evolution Header Set converts the slip-on system into a full system designed to give noticeably increased power at higher revs. Handcrafted titanium headers incorporate 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Header Set utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, it delivers a sportier and hard-hitting sound, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance.
When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.
NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only.
