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

Unleash the hidden power and tone of your Porsche 718 GT4, Spyder, or GTS 4.0L with 718 Street Headers by SOUL Performance Products. Designed for street use with track-tested results, this system enhances sound, torque, and throttle response—without sacrificing daily comfort.

Whether you’re carving through back roads or enjoying a spirited Sunday drive, these headers provide noticeable improvements from the moment you start the engine.

Built for Street Power with Track DNA

Unlike race-only setups, these high-performance headers balance flow and compliance. They feature mandrel-bent T304L stainless steel construction and include 200-cell HJS catalytic converters that support emissions needs without choking performance.

This Porsche header upgrade improves midrange torque and throttle feedback, making your 4.0L flat-six feel more alive—especially under load. Drivers will notice a sharper tone under acceleration, while cruise mode remains refined enough for long-distance driving.

• ✅ Dyno-proven gains: +15–20 whp / +15–25 wtq

• ✅ Fabricated from T304L stainless steel

These performance headers bolt directly to your factory system, requiring no cutting or permanent modification. As a result, installation is straightforward—and fully reversible.

To unlock their full potential, pair them with a SOUL Valved Exhaust System or a Cobb Accessport tune for optimal power and CEL-safe operation.

Ideal for Enthusiasts Who Drive

If you want an exhaust setup that balances performance and practicality, this header set is for you. It provides the deep sound and added power Porsche drivers crave, while maintaining OEM fit and street legality in most regions.
