Porsche 981 Cayman GT4 Sport Headers

Product description

HJS German imported catalytic converters are made from some of the highest quality materials you can find in a catalytic converter. This provides high performance gains and a long service life, so it does not deteriorate over time like lower quality catalytic converters. These catalysts flow up to 93-95% of a straight pipe in most applications. The advantage is that you get the "straight pipe sound" while still being able to scrub enough emissions to keep the engine from burning.

Low-end power and sound you can enjoy every day! The perfect complement to Fabspeed's factory exhaust system or 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 standards.

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 into significantly better acceleration and throttle response when pulling away from a stoplight or merging onto your favorite highway. Thanks to the world-class performance of the HJS catalytic converter cores, your GT4 will maintain emissions standards in most regions and won't 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 overall volume and tone.
