Porsche Cayman GT4 Sport Headers

Low-end power and sound that you can enjoy every day! The perfect complement to either the factory exhaust system or Fabspeed’s performance exhaust systems, these high-flow headers are designed around HJS catalytic converters, making them the best upgrade for more enjoyable street driving and emissions compliance. 

Designed with noticeable street performance in mind, these Sport Headers provide an additional 26 whp and 39 ft/lbs of torque at 3600 RPM. This translates to significantly better acceleration and throttle response when powering away from a stop light or merging onto your favorite highway. Thanks to the world-class performance of the HJS catalytic converter cores, your GT4 stays emissions-compliant in most regions and will not throw a Check Engine Light.

In addition to the performance gains, Fabspeed's GT4 Sport Headers also add great character to the exhaust note by improving the overall volume and tone.
