Porsche 718 GT4 Sport Header Package – Precision Performance and Aggressive Sound

Unlock the full potential of your GT4 with the Porsche 718 GT4 Sport Header Package. Engineered to deliver noticeable gains in power, response, and sound. This performance upgrade replaces the restrictive factory manifolds with free-flowing headers designed to improve exhaust flow. Increase horsepower and enhance throttle response across the rev range.

Crafted from high-grade T304 stainless steel, the Porsche 718 GT4 Sport Header Package features long tube runners and CNC-machined merge collectors for optimal exhaust velocity and performance. Whether you’re hitting the track or carving up mountain roads. This package transforms the driving experience with sharper engine response and a deeper, more aggressive exhaust note.

Designed to fit seamlessly with both OEM and aftermarket exhaust systems, these headers offer bolt-on performance without compromise. Pairing the headers with a proper ECU tune removes factory limitations and helps you extract maximum output from the GT4’s naturally aspirated flat-six engine.

Whether you’re chasing lap times or just want to hear your GT4 sing, the Porsche 718 GT4 Sport Header Package delivers motorsport-inspired performance in a street-ready form.

For the standard 718 GT4, we offered both a catted and catless solution for a header replacement. But to follow suit with the GT4 RS, which would introduce necessary compromises, we didn’t do it. For a transformative solution that still retains catalytic converters. We’ve developed our Sport Header Package that combines our unrestricted Competition Headers with our Sport Cat Over Axle Pipes.

Our Competition Headers maximize the design potential of that section of the GT4 RS, utilizing all the space available for longer tubing and an expanded merge collector to meet the 3-inch flowpath of the Over Axle Pipes, and our Sport Cat Over Axle Pipe with high-flow cats deliver tangible sound and performance gains as it replaces the empty particulate filter on the factory units.
