Porsche 981 Cayman GT4 Sport Headers

Product description

HJS German Imported Catalytic Converters are made from some of the highest quality materials you will find in a catalytic converter. This provides high performance gains and long life so it will not deteriorate over time like lower quality catalytic converters. These catalytic converters will flow up to 93-95% of a straight pipe in most applications. The benefit is that you get that “straight pipe sound” while still being able to scrub enough exhaust to prevent engine fires.

Low-end power and sound you can enjoy every day! These high-flow headers are the perfect complement to the factory exhaust system or Fabspeed performance exhaust systems and are designed around HJS catalytic converters, making them the best upgrade for smoother street riding and emissions compliance.

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

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