Upgrade your Porsche Cayman GT4 RS with these top-of-the-line Fabspeed RENNKRAFT long tube headers.
With over 30 years of Porsche engineering experience, Fabspeed created a true long tube header system that features an HJS 200 cell tri metallic sport catalytic converter. Experience improved performance and a more aggressive exhaust note.
The seamless long tube design and advanced HJS catalytic converters deliver significant power gains, while remaining CEL-free. A perfect balance of power and efficiency.
A patented RENNKRAFT® system makes it simple to switch between cats and cat bypass pipes, perfect for both daily driving and track days.
Plus, the bi-layer heat shielding withstands up to 2400F/1300C, minimizing radiant heat for improved performance.
This system will give your Cayman GT4 RS a deep, aggressive tone you will love. Keep the factory muffler and easily control the volume with PSE (Porsche Sport Exhaust) technology.
These headers also pair perfectly with Fabspeed's Valvetronic X-pipe, giving you a powerful and aggressive exhaust note, while still allowing you to control the volume with the PSE button.
Crafted with equal length tubes and high velocity merge collectors. Made with mandrel bent T304 stainless steel tubing. Bi-layer heat shielding of ceramic fiber and stainless steel protects for optimal performance.
A clever modular design with a V-band clamp for easy conversion between HJS catalytic converters and cat bypass pipes.
This allows for fast switching for track events, preventing catalytic converter damage during track use.
Easy bolt-on project. No cutting or welding required. An ECU tune is not needed after installation.
