Product Description

 

 

The SOUL Competition Over-Axle Pipes for the 718 GT4 RS / Spyder RS transform the restrictive factory exhaust into a fully free-flowing 3-inch system — delivering a raw, aggressive flat-six soundtrack and unlocking the 4.0L’s full performance potential. By eliminating redundant secondary catalytic cores and the unnecessary particulate-filter chambers, these over-axle pipes reduce exhaust back-pressure and heat soak while significantly improving exhaust flow. Machined from thick-wall T304L stainless steel with mandrel bends and precision flanges, this bolt-on upgrade is engineered for both street & track use and backed by SOUL’s lifetime warranty.

Fitment Notes

  • Designed for 2022+ Porsche 718 GT4 RS / Spyder RS (fits with factory or upgraded headers/rear exhaust) 

  • Replaces the factory over-axle pipe section — removing factory particulate filter cores and secondary cats.

  • Bolt-on installation with included hardware; no cutting or welding required. 

  • For maximum reliability, a thermal‐management solution is strongly recommended due to increased heat output from the GT3-derived engine.

Included

  • Full over-axle pipe assembly, mandrel-bent stainless (T304L) with ovalized 3″-diameter tubing designed to fit under 718 RS suspension and body clearance constraints.

  • Precision-cut stainless flanges, gaskets, and all required mounting hardware for direct installation.

  • Quality packaging and protective packing foam to ensure damage-free delivery and avoid bent or warped sections during shipping/handling.

Product Specs

  • Material: T304L stainless steel, thick-wall, mandrel-bent for smooth flow and durability.

  • Flow path diameter: Full 3.0 inches (flange-to-flange) using oval tubing for clearance compliance.

  • Weight savings: ~ 13.3 lbs (~6 kg) less than factory over-axle pipe assembly (manufacturer’s stated spec 11.65 lbs vs 25 lbs OEM). 

  • Emissions / Code: No check-engine light on North American cars when installed. ECU tuning required for cars in regions with monitored emissions sensors.

Product Features

  • Maximized Exhaust Flow — Full-diameter 3″ oval tubing clears the restrictive OEM particulate-filter cores, improving exhaust scavenging and reducing backpressure. 

  • Enhanced Exhaust Tone & Character — The freer flow unlocks a louder, more muscular flat-six soundtrack, delivering the aggressive growl and crackle GT-car fans crave.

  • Weight Reduction for Better Dynamics — Shedding over 13 lbs from the rear exhaust mass reduces weight, improving throttle response, transient response, and chassis balance.

  • Bolt-on, OEM-Friendly Install — Designed to bolt onto existing exhaust layout using factory or aftermarket headers/rear exhaust; no cutting or welding required. 

  • Street & Track Usable — While delivering track-ready flow and sound, the design remains practical for street use. For those pushing hard, thermal management options (wrapping or coating) are available to protect surrounding components. 

  • Lifetime Warranty — Built and tested in-house in the USA, with quality control and longevity in mind.
