Product Description

 

 

The Soul 718 GT4 RS / Spyder RS Valved Exhaust System replaces the restrictive factory rear muffler and exhaust piping with a free-flowing, 3-inch-oval tubing layout and a bespoke valve-controlled rear section — giving your 718 GT4 RS / Spyder RS a dynamic dual-tone personality. With valves closed, it delivers a balanced, street-friendly exhaust note; with valves open, it unleashes a raw, aggressive GT3-like bark, deeper burbles on decel, and a rich flat-six soundtrack under load. The result: sharper throttle response, improved exhaust flow, and the dramatic transformation in exhaust character that turns your RS-car into a true enthusiast’s weapon.

Fitment Notes

  • Designed specifically for Porsche 718 GT4 RS / Spyder RS (2022 +).

  • Requires aftermarket over-axle pipes (or compatible aftermarket exhaust plumbing) for proper fitment — not compatible with factory over-axle pipes. 

  • Works with factory headers (or aftermarket headers) and integrates with the car’s existing exhaust valve controls (or independent valve controller if preferred).

Included

  • Full stainless-steel rear exhaust section: 3″ oval tubing, X-pipe merger, and valved muffler designed to fit 718 RS chassis. 

  • Valve assembly (vacuum- or controller-actuated, depending on factory setup).

  • Hardware and mounting flanges to mate with GT4 RS / Spyder RS rear under-body structure and existing or modified exhaust plumbing. 

  • Option to select aftermarket performance exhaust tips designed to match the full 3″ flow; compatible with (but not ideal for) stock tips.

Product Specs

  • Tubing size: 3.0-inch oval, full-flow throughout rear section to maximize exhaust flow and minimize restriction.

  • Construction: Mandrel-bent T304L stainless steel with precision TIG-welded seams; pipe geometry designed to maximize flow while fitting in 718 RS rear chassis. 

  • Exhaust configuration: X-pipe merger for balanced exhaust flow and improved scavenging, enhancing tone and throttle response. 

  • Valve operation: Dual-mode — muffler path for “valves closed” (quiet / civilized sound), direct-flow path for “valves open” (full performance sound). 

  • Weight: Designed to be similar to OEM rear exhaust system (or slightly lighter depending on tip/pipe configurations), minimizing added mass while improving flow.

Product Features

  • Dual-Mode Exhaust Tone — Switch between a refined, daily-driver-friendly exhaust note with valves closed and a raw, aggressive GT-inspired roar with valves open — giving you flexibility depending on mood, time, or location. 

  • Full 3" Flow & Improved Throttle Response — Oversized oval piping and X-pipe design reduce back-pressure, allowing the 4.0 L flat-six to breathe better — resulting in sharper throttle response and fuller exhaust sound under load. 

  • Anti-Drone Muffler Design — The exhaust includes a Helmholtz-type secondary flow path to minimize drone at cruising speeds — allowing a sporty exhaust character without cabin fatigue. 

  • Track-Ready Sound & Performance Potential — With valves open (and especially when paired with over-axle pipes or upstream mods), the system unlocks the motorsport heritage of the GT4 RS’s flat-six — ideal for canyon runs, track days, or spirited driving. 

  • OEM-Quality Fitment & Versatility — Designed to bolt into the GT4 RS chassis without extensive fabrication; compatible with factory or aftermarket headers and exhaust plumbing for a tailored build path.

  • Lifetime Warranty — As with all Soul Performance exhaust components, this system is backed by a lifetime warranty for both street and track use — giving prospective buyers confidence in durability and longevity.
