Manifold Genuine Porsche part 982254018DX

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.

Fabspeed Street Performance Package 718 GT4 / GTS / Spyder 2020+

For late model exhaust brackets



Fabspeed's 718 Street Performance Package is the premium solution for adding dynamic performance and superlative sound to your GT4 / GTS / Spyder on the street. Delivering well over 400 horsepower to the wheels with easy-to-install bolt-on upgrades (on a GT4), there is no better option for the GT4 owner seeking maximum power and performance while retaining catalysts and the stock ECU tune. No need to suffer long periods of downtime for an engine build. Simply install the Fabspeed 718 Street Performance Package and get all the power you need. Fully street and racetrack tested on PDK and Manual cars!

SOUND:

With PSE (Porsche Sport Exhaust) on and the valves open, this system turns the 4.0L's exhaust note into a truly exotic sound with a significant increase in volume. This system will turn heads as you rip by, some jeers from the nearby pedestrians may have you hitting the accelerator a little more often. Tolerable enough for street driving and highway cruising but definitely not a subtle sunday-mass regular.

POWER:

After many dyno hours and incremental refinements to our design we were able to achieve dyno gains of 27 WHP and 19 FT/LBS of TQ at 7500 RPM. Best of all, power gains are seen as low as 3700 RPM, so there are power gains across the entire power band!

INCLUDES:

• Fabspeed Valvetronic X-Pipe Exhaust
• Fabspeed RENNKRAFT™ Modular Street and • Racing Headers with HJS Catalytic Converters
• Fabspeed Over Axle GPF Delete Pipes

• Fabspeed is not responsible for miles per gallon lost, however; smiles per gallon gained is entirely our fault
• Optimized for maximum performance with no check engine light, guaranteed (USA Models Only, EU models please inquire)
• Choose between real Carbon Fiber, Satin Black, Polished Stainless, Brushed Stainless, or Re-use your OEM tips
