Experience enhanced performance and a captivating sports car exhaust note on a daily basis, while remaining compliant with emissions regulations.
The perfect complement to either the factory exhaust system or Fabspeed's performance exhaust systems.
These high-flow headers are designed around HJS German, European certified catalytic converters, making them the best upgrade for enjoyable street driving and emissions compliance.
Designed with noticeable street performance in mind, these sport headers provide an additional 26 wheel horsepower and 39 lb/ft of torque at 3600 RPM.
This leads to a noticeable increase in acceleration and throttle response, ideal for quickly accelerating from a stop or merging onto a busy highway.
Thanks to the world-class performance of the EMITEC tri-metallic 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.
