Description
Unlock the full auditory and driving potential of your Porsche 718 GT4, Spyder, or GTS 4.0L with the SOUL Valved Exhaust System. Designed for enthusiasts who demand versatility, sound quality, and uncompromising craftsmanship, this exhaust system delivers two distinct driving personalities—mild and wild—at the push of a button. Whether you’re cruising comfortably or chasing high-RPM thrills, the SOUL system enhances the driving experience with a refined, GT3-inspired tone and precision-tuned acoustics.
The bespoke X-pipe design enables a smooth, high-pitched exhaust note when the valves are open, adding excitement and depth to acceleration. With the valves closed, the exhaust flow is redirected through a custom-engineered muffler that controls resonance and drone, delivering a more subdued, yet still present tone for everyday driving. Built to complement other aftermarket components such as headers and over axle pipes, this system integrates seamlessly into any performance setup.
Developed entirely in-house, the SOUL Valved Exhaust System is constructed from mandrel-bent .065” wall T304L stainless steel and TIG-welded with premium ARCAL™ Prime argon gas for unmatched durability and weld integrity. Precision water jet cut flanges meet ISO 9001:2015 standards, ensuring a perfect fit and long-term reliability. The internal muffler design includes straight-through perforated tubing and sound-absorbing packing for maximum flow and acoustic balance.
This exhaust system provides a noticeable change in tone even when paired with stock over axle pipes, producing a smoother, more resonant sound profile that reflects the true character of the 4.0L flat-six engine. When paired with SOUL Competition Over Axle Pipes, the transformation becomes profound—offering an exhilarating GT3-style note with tasteful burbles on deceleration and visceral crackles during gear changes, all while maintaining civility during light throttle cruising.
A SOUL Valve Controller Kit is highly recommended to unlock full control of the exhaust valves, allowing you to experience the refined tones at lower RPMs and fully appreciate the sound design across the rev range.
