SOUL Performance Products Sport Cat Over Axle Pipes offer a unique solution for Porsche 718 Cayman GT4 RS and 718 Spyder RS owners looking for increased sound and performance while retaining monitored catalytic converters in the exhaust system.
Rather than replacing the factory headers with a catted header design, SOUL relocates the high-flow catalytic converters to the over-axle section. This modular approach allows the Sport Cat Over Axle Pipes to be used with the factory headers or paired with SOUL Competition Headers for a more comprehensive exhaust upgrade.
As a standalone upgrade, the Sport Cat Over Axle Pipes replace the factory particulate-filter assemblies with a freer-flowing design incorporating high-flow catalytic converters. The result is increased exhaust sound and reduced restriction while retaining catalytic converters downstream in the exhaust system.
For a more aggressive configuration, pairing the Sport Cat Over Axle Pipes with SOUL Competition Headers removes the factory catalytic converters at the headers while retaining the monitored high-flow catalytic converters within the over-axle pipes.
Because catalytic converters generate considerable heat, SOUL includes its heat solution as standard equipment with every set of Sport Cat Over Axle Pipes.

Mandrel-bent tubing
Back-purged TIG-welded construction
Precision water-jet-cut flanges
Flanges manufactured to ISO 9001:2015 standards
Flange tolerances of approximately ±0.003 inch
Fixture-built to maintain dimensional accuracy during welding
Quality checked and fixture tested prior to shipment
New high-grade installation hardware included
Designed and built in-house in Willow Grove, Pennsylvania
No check engine light expected on North American-market vehicles
ECU tuning required for European-market vehicles
Backed by SOUL Performance Products' Lifetime Warranty for street and track use
SOUL developed the Sport Cat Over Axle Pipes as an alternative to using catalytic converters within replacement headers.
With the factory headers retained, the Sport Cat Over Axle Pipes add high-flow catalytic converters while replacing the factory particulate-filter section.
When combined with SOUL Competition Headers, the factory header-mounted catalytic converters are removed and the high-flow catalytic converters within the Sport Cat Over Axle Pipes remain in the exhaust system.
This gives GT4 RS and Spyder RS owners the ability to build the exhaust system in stages while maintaining compatibility between the factory and SOUL components.
