The SOUL Weissach-Style Bolt-On Exhaust Tips are a clean visual and functional upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. They give the rear of the car the aggressive Weissach motorsports-style look while using durable 304L stainless steel construction for long-term street and track use.

SOUL developed these tips after working with a GT4 RS equipped with the factory Weissach Package and titanium exhaust tips. The factory Weissach tips look great, but titanium exhaust tip designs can be more prone to fin cracking from repeated heat cycling, especially on cars that see sustained track use. SOUL’s stainless steel design gives customers a more durable solution while preserving the high-end Weissach-style appearance.

These tips are available for both factory-style 2.25-inch outlet systems and SOUL 3-inch outlet systems. That makes them useful whether you are upgrading the appearance of a mostly factory exhaust setup or finishing off a full SOUL exhaust system with tips that match the larger 3-inch flow path.

DasMotoring Notes

These tips are a great choice if you want the Weissach-style look without using the factory titanium tips. They are especially appealing for cars that see aggressive driving or track use, where repeated heat cycling can be hard on titanium finned tip designs.

If you are running a factory rear exhaust or another exhaust with factory-size outlets, choose the 2.25-inch version. If you are running a SOUL exhaust system with the larger 3-inch outlet path, choose the 3-inch version so the tips do not create an unnecessary neck-down restriction.

For full SOUL exhaust builds, DasMotoring recommends using the SOUL 3-inch tip configuration whenever possible to preserve the larger exhaust flow path and avoid reducing the system near the outlet.

The SOUL Performance Package is the most complete SOUL exhaust upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This package is designed for owners who want to transform the full exhaust system from the headers back, unlocking more sound, sharper response, improved flow, and a much more aggressive RS driving experience.

This package combines SOUL Competition Headers, SOUL Over Axle Pipes, and the SOUL Valved Exhaust System. Instead of upgrading only one section of the exhaust, the Performance Package addresses the full exhaust path: the factory headers, the over-axle section, and the rear muffler system.

The result is SOUL’s most comprehensive exhaust solution for the GT4 RS and Spyder RS. With the valves open, the car delivers a louder, sharper, more motorsports-inspired tone from the GT3-derived 4.0L flat-six. With the valves closed, the SOUL Valved Exhaust System helps reduce volume and unwanted resonance for more comfortable street driving.

Competition vs. Street Package

Choose the Competition Package if your priority is maximum sound, maximum flow, and the most aggressive configuration. This is the more raw setup and is best suited for customers who want the loudest and most unrestricted SOUL package.

Choose the Street Package if you want the most complete SOUL exhaust experience while keeping the setup more street-conscious. This is the better choice for owners who want major sound and performance gains while retaining catalytic converters in the over-axle section.

DasMotoring Notes

This is the top-tier SOUL exhaust package for the GT4 RS and Spyder RS. If you are planning to upgrade headers, over-axle pipes, and the rear exhaust, this is the cleanest way to buy the full system as a matched package.

For most street-driven cars, DasMotoring recommends the Street Package configuration. It still delivers a dramatic change in sound and response, but it is the more street-conscious option. If your goal is maximum volume and the most aggressive setup, choose the Competition Package.

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, the included heat solution is an important part of this package, especially for cars that will see aggressive street driving, track use, or extended high-load operation.

Emissions requirements vary by location and vehicle use. Please confirm your local requirements before ordering.

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.

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.

The SOUL Valved Exhaust System is a premium rear exhaust upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This is the ideal setup for owners who want a major improvement in sound and flow, but still want the ability to quiet the car down when needed.

From the factory, the GT4 RS and Spyder RS use a rear muffler layout carried over from the standard 718 GT4. While that works for factory noise limits and production requirements, it does not fully unlock the character of the GT3-derived 4.0L engine. SOUL’s Valved Exhaust System replaces the factory rear muffler section with a freer-flowing design using full 3-inch oval tubing to fit within the tight rear chassis area.

With the valves open, the system delivers a sharper, louder, more motorsports-inspired exhaust note. With the valves closed, the system is designed to reduce volume and help make the car more comfortable for street driving. SOUL also designed the secondary flow path as an anti-drone chamber to help reduce unwanted resonance.

DasMotoring Notes

This is the best SOUL rear exhaust choice for GT4 RS and Spyder RS owners who want more sound and performance potential without going to a fixed-volume race exhaust. If you want the car to have two personalities — louder and more aggressive with the valves open, calmer with the valves closed — this is the setup to choose.

Because this system is not compatible with factory over-axle pipes, make sure your build includes SOUL Competition Over Axle Pipes, SOUL Sport Cat Over Axle Pipes, or another compatible aftermarket over-axle pipe option.

SOUL allows this system to be configured with OEM exhaust tips, but the factory tips have a smaller inlet diameter. Reusing the OEM tips requires the system to neck down near the tips, which creates a restriction. For best performance and flow, DasMotoring recommends selecting SOUL’s matching high-flow tips instead of reusing the factory tips.

The SOUL Race Exhaust System is a lightweight, high-flow rear exhaust upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This system is designed for owners who want to unlock more sound, more flow, and a sharper motorsports character from the GT3-derived 4.0L flat-six.

From the factory, the GT4 RS and Spyder RS reuse a rear muffler layout based around the standard 718 GT4. While that setup helps meet factory sound and production requirements, it also limits the full character of the RS engine. SOUL’s Race Exhaust System replaces the factory rear exhaust section with a freer-flowing design that maintains a full 3-inch flow path from the flanges through the tips.

The result is a more aggressive, more emotional exhaust note with a crisp motorsports tone. SOUL’s bespoke X-pipe design helps bring out the high-rpm character of the 4.0L engine, while the optional resonated version adds resonators and anti-drone tubes to help reduce unwanted low-rpm frequencies.

DasMotoring Notes

This is the right choice for GT4 RS and Spyder RS owners who want a more aggressive rear exhaust setup with less weight and more sound than the factory muffler. If you want the most raw version, choose the non-resonated configuration. If the car will see street use and you want to reduce low-rpm resonance, the resonated version is the safer choice.

SOUL notes that this system can be configured to reuse the factory exhaust tips, but the factory tips have a smaller inlet diameter. That requires the system to neck down near the tips, which introduces a restriction. For best performance and flow, DasMotoring recommends selecting SOUL’s matching high-flow exhaust tips instead of reusing the OEM tips.

For a full sound-focused setup, pair this Race Exhaust System with SOUL Competition Over Axle Pipes or choose the SOUL Race Exhaust Package.

The SOUL Sport Header Package is a complete header and catted over-axle pipe upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This package combines SOUL Competition Headers with SOUL Sport Cat Over Axle Pipes, giving the car a major improvement in sound, response, and exhaust flow while still retaining catalytic converters in the over-axle section.

For the GT4 RS and Spyder RS platform, SOUL chose not to compromise the header design with a catted header replacement. Instead, this package uses unrestricted Competition Headers paired with high-flow catted over-axle pipes. The headers maximize the available space with longer tubing and an expanded merge collector, while the Sport Cat Over Axle Pipes replace the factory over-axle / particulate filter section with a freer-flowing catted design.

The result is one of the best balanced exhaust upgrades for the GT4 RS and Spyder RS: more character, sharper response, better flow, and a more aggressive sound without moving to a fully catless over-axle setup.

DasMotoring Notes

This is the package I would recommend for GT4 RS and Spyder RS owners who want a serious exhaust upgrade while keeping catalytic converters in the system. Compared with only changing the over-axle pipes, this package also opens up the header section, giving the car a more complete change in sound, response, and flow.

For maximum sound and flow, consider the SOUL Competition Headers paired with SOUL Competition Over Axle Pipes instead. For a more street-conscious setup that still delivers a big jump in character, this Sport Header Package is the better choice.

SOUL states that the Sport Cat Over Axle Pipes are not expected to trigger a check engine light on North American cars, while European-market cars require ECU tuning. Emissions requirements vary by location and vehicle use, so please confirm local requirements before ordering.

The SOUL Competition Headers are a premium performance header upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. Designed specifically around the GT4 RS / Spyder RS exhaust layout, these headers improve sound, flow, response, and weight compared with the factory header assemblies.

For the GT4 RS and Spyder RS platform, SOUL chose to maximize the header section rather than compromise the design with a catted header solution. These Competition Headers use longer tubing and an expanded merge collector designed to meet the 3-inch flow path of the over-axle pipes. The result is a more efficient, freer-flowing header design that pairs with factory or upgraded over-axle pipes.

As a standalone upgrade, these headers sharpen the car’s sound and response. For a more complete setup, they can be paired with SOUL Sport Cat Over Axle Pipes, SOUL Competition Over Axle Pipes, or a full SOUL exhaust package depending on your sound, emissions, and performance goals.

DasMotoring Notes

These are the right choice if you want to increase sound, response, and exhaust flow from the header section of your GT4 RS or Spyder RS. For a catted performance setup, pair these with SOUL Sport Cat Over Axle Pipes. For maximum sound and flow, pair them with SOUL Competition Over Axle Pipes.

Because these headers move the car further away from the factory exhaust configuration, DasMotoring recommends choosing the rest of the exhaust setup carefully based on your intended use, desired sound level, and local emissions requirements. Emissions legality varies by location and vehicle use, so please confirm your local requirements before ordering.

The SOUL Sport Cat Over Axle Pipes are a high-flow catted over-axle upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. This is an excellent option for owners who want more sound, better exhaust flow, and a more engaging driving experience while still retaining catalytic converters in the over-axle section.

On the GT4 RS and Spyder RS, SOUL chose not to build a catted header replacement. Instead, they developed a modular over-axle pipe with integrated high-flow catalytic converters. This allows the factory or upgraded headers to be paired with a freer-flowing catted over-axle section, creating a strong balance between performance, sound, and emissions-conscious design.

As a standalone upgrade, these Sport Cat Over Axle Pipes replace the factory empty particulate filter section and deliver a noticeable increase in sound and response. When paired with SOUL Competition Headers, they create a much more aggressive performance setup while still retaining a monitored catalytic converter.

Each set includes a heat solution as standard to help manage the additional heat generated by the catalytic converter core.
