Exhaust Sport Headers. Porsche 981 Cayman GT4 / Boxster Spyder ❭ FSPOR981GT4SHDR
- Porsche Cayman GT4 3.8L 2015-16

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.
FEATURES:
• Fits all Porsche 981 Cayman GT4 / Boxster Spyder vehicles (2015+)
• Includes German-imported 200-cell HJS Sport • Catalytic Converters for maximum performance and reliability
• Adds 26 whp and 39 ft-lbs of torque at 3600RPM, providing significantly better performance during street acceleration
• Constructed from equal-length T304 stainless steel C.N.C. mandrel-bent tubing for improved torque and equalized engine pulsing
• More power and torque across the RPM band and dramatically improved exhaust sound
• Direct replacement for the OEM headers with no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
PLEASE NOTE: Fabspeed's 200-cell high-flow catalytic converters are not C.A.R.B. certified and are for Off-Road Use ONLY in the state of California. Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.
Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.
