718 Competition Headers – SOUL Performance for Porsche GT4 / Spyder / GTS 4.0L

Upgrade your Porsche 718 GT4, Spyder, or GTS 4.0L with 718 Competition Headers by SOUL Performance—built to push your flat-six engine to its full potential. These headers are crafted for serious enthusiasts who want power, response, and race-ready tone in one package.

If you demand performance gains without compromise, this upgrade is the perfect match.

Unmatched Flow and Response

Unlike factory manifolds that restrict exhaust velocity, these headers use T304L stainless steel and mandrel-bent runners to maximize flow. Because the design eliminates catalytic converters, the exhaust path is completely unobstructed. As a result, you get sharper throttle response and a more aggressive tone that amplifies every gear change.

Moreover, the catless design reduces backpressure significantly, helping your 4.0L engine breathe freely. Power gains of +20–25 whp and +20–30 wtq are dyno proven, especially in the midrange.

Why Choose 718 Competition Headers?

• ✅ Designed for Porsche 718 GT4 / Spyder / GTS 4.0L (2020+)

• ✅ Made from T304L stainless steel, TIG welded in the USA

• ✅ Catless setup for optimal exhaust velocity

• ✅ Proven +25 whp and +30 wtq with supporting mods

• ✅ Works with both OEM and aftermarket systems

• ✅ Ideal for track-focused and off-road applications

Although these headers are not road legal, they’re perfect for performance builds where emissions aren’t a concern. To prevent check engine lights and maximize gains, we strongly recommend pairing them with a Cobb Accessport or M-Engineering tune.

Additionally, when installed alongside a SOUL Valved Exhaust, the result is a truly race-inspired driving experience.

Made for Maximum Impact

If your goal is sharper response, louder tone, and race-grade airflow, look no further. These 718 Competition Headers offer all of that while maintaining a bolt-on installation. Because there’s no cutting or welding required, you can install them with ease and confidence.

For a complete track package, consider pairing with Eventuri carbon intakes, titanium exhaust tips, or upgraded engine mounts. Together, these parts will transform your Porsche into a precision machine—both in sound and performance.
