Product Description

 

 

The SOUL Resonated Over‑Axle Pipes for the 718 GT4 RS / Spyder RS discard the stock restrictive over‑axle pipes (with redundant cats/filters) and replace them with a full‑3‑inch, mandrel‑bent stainless exhaust flow path — significantly improving exhaust flow and sound while reducing unsprung/rotating mass. These resonated pipes give a refined yet aggressive exhaust note, delivering a balanced performance upgrade that enhances throttle response, reduces exhaust restriction, and tames drone for streetable usability. With improved flow and lighter weight, they unlock more of the flat‑six’s potential under both spirited driving and regular use.

Fitment Notes

  • Intended for Porsche 718 GT4 RS / Spyder RS (2022+ and up) using factory or upgraded headers / rear exhaust. 

  • Direct‑bolt swap — fits to factory mounting points without special fabrication.

  • As exhaust flow increases and heat rises, user is recommended to consider thermal‑management solutions (heat wrap or coating) to protect surrounding components.

Included

  • Full set of over‑axle pipes (left & right) built from thick-wall, T304L stainless steel — mandrel‑bent tubing sized for full 3‑inch flow. 

  • Resonator chambers integrated into the piping to smooth and moderate exhaust tone and reduce cabin drone.

  • All required flange hardware and gaskets for direct bolt‑on installation.

Product Specs

  • Tubing diameter: 3.0 inch throughout the over‑axle section (ovalized where necessary for fitment). 

  • Construction: Mandrel‑bent, thick‑wall T304L stainless steel; TIG‑welded under back‑purged argon for maximum strength and longevity. 

  • Weight savings: Approximately 8.25 lbs (3.74 kg) lighter than the factory over-axle pipe assembly (16.75 lb vs. 25 lb). 

  • Sound control: Integrated resonator chambers to moderate volume and reduce low‑frequency drone while preserving a sporty exhaust note under load.

Product Features

  • Improved Exhaust Flow & Engine Responsiveness — By removing restrictive factory cats/filters and using full‑diameter 3″ tubing, exhaust gases exit more freely, reducing back‑pressure and improving throttle response and rev‑up. 

  • Aggressive but Controlled Exhaust Tone — The resonated design preserves the flat‑six’s character under throttle while managing drone and cabin resonance for comfortable daily driving.

  • Weight Reduction for Better Dynamics — Shedding over 8 lbs from the exhaust system helps reduce rotational and unsprung mass, which can slightly sharpen handling response and reduce inertia. 

  • Bolt‑On, OEM‑Friendly Fitment — Designed for direct installation with factory or upgraded headers/rear exhaust — no custom fabrication or aftermarket mounts required.

  • Durable, Long‑Lasting Construction — Thick-wall stainless construction and professional TIG‑welding ensure the system will withstand repeated heat cycles and stress from spirited or track driving. 

  • Street & Track Versatility — Balanced for both performance driving and daily usability, offering a middle ground between aggressive “race only” exhausts and overly tame stock setups.
