The SOUL Street Package is the complete valved rear exhaust package for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This setup is designed for owners who want a major increase in sound, flow, and character, but still want the ability to quiet the car down for cruising.
This package combines SOUL Over Axle Pipes with the SOUL Valved Exhaust System, replacing the factory over-axle pipes and rear muffler section. With the valves open, the system delivers a sharper, louder, more motorsports-inspired tone from the GT3-derived 4.0L flat-six. With the valves closed, SOUL’s anti-drone chamber design helps reduce unwanted resonance and makes the car more comfortable for street driving.
The Street Package maintains a full 3-inch flow path through the rear exhaust system when paired with SOUL’s matching high-flow tip options. The over-axle pipe section can be configured for more sound or a smoother, more refined tone depending on your selected options.

DasMotoring Notes
This is the SOUL package I would recommend for GT4 RS and Spyder RS owners who want the best balance of sound, performance, and street usability. It is a much bigger upgrade than only changing the rear exhaust because it also replaces the factory over-axle pipes, which are one of the key restrictions in the RS exhaust system.
For most street-driven cars, DasMotoring recommends selecting the resonated configuration. It still gives the car a major change in character, but with a smoother tone and better control of unwanted low-rpm resonance. If your goal is maximum sound and aggression, choose the non-resonated version.
SOUL allows this package to be configured with OEM exhaust tips, but the factory tips use a smaller inlet diameter. Reusing OEM tips requires the system to neck down near the tips, which creates a restriction. For best sound, flow, and performance, DasMotoring recommends choosing SOUL’s matching high-flow exhaust tips.
Because the GT4 RS and Spyder RS generate significant exhaust heat, DasMotoring strongly recommends adding the heat solution for the over-axle pipes, especially on cars that will see aggressive street driving, track use, or extended high-load operation.
SOUL states that North American cars are not expected to trigger a check engine light with this package. European-market cars require ECU tuning. Emissions requirements vary by location and vehicle use, so please confirm local requirements before ordering.
