The SOUL Race Exhaust Package is the maximum-sound rear exhaust package for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This package combines SOUL Competition Over Axle Pipes with the SOUL Race Exhaust System to remove the major factory exhaust bottlenecks behind the headers.
The GT4 RS and Spyder RS use a GT3-derived 4.0L flat-six, but the factory exhaust system still has several production-car restrictions. The factory over-axle section contains flow restrictions, and the rear muffler design is based around the standard 718 GT4 layout. SOUL’s Race Exhaust Package replaces both sections with a freer-flowing, lightweight system designed to let the RS engine sound and breathe like it should.
This package uses SOUL’s oval Competition Over Axle Pipes and Race Exhaust System to maintain a full 3-inch flow path through the rear exhaust. The result is a much louder, sharper, more motorsports-inspired exhaust note with reduced weight and improved flow compared with the factory components.

DasMotoring Notes
This is the package to choose if your goal is maximum sound, maximum flow, and the most aggressive rear exhaust setup from SOUL without changing the headers. It is significantly more aggressive than only replacing the rear exhaust, because it also removes the restriction in the factory over-axle section.
For street use, DasMotoring generally recommends the resonated version unless you specifically want the loudest possible setup. The non-resonated version is the more raw, lightweight, track-focused choice.
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 performance and flow, DasMotoring recommends choosing SOUL’s matching high-flow tips.
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.
Because the GT4 RS and Spyder RS generate significant exhaust heat, SOUL strongly recommends using a thermal management solution on over-axle pipe products to help protect nearby components and bodywork.
