Product Description

 

 

The SOUL Valved Exhaust System for 718 GT4 / Spyder / GTS 4.0L radically enhances the character of your flat-six while keeping flexibility for daily driving. Its smart valved design gives you two distinct driving profiles: a refined, low-drone mode for everyday roads and a high-pitched, aggressive “track-ready” tone when you open the valves. Built from heavy-duty T304L stainless steel and featuring a bespoke X-pipe + muffler combo, the system balances exotic exhaust tone with street-usable comfort — giving your 718 a true sports-car soundtrack without sacrificing usability.

Fitment Notes

  • Engineered for Porsche 718 GT4, Spyder, GTS 4.0L (2020+) models. 

  • Includes valve controller kit for cars lacking factory exhaust valve (or for overriding factory valve logic).

  • Direct bolt-on fitment — uses existing exhaust mounting points. 

  • Designed to work well with stock or aftermarket over-axle pipes / downpipes; choice of tips available depending on spec.

Included

  • Full stainless-steel exhaust system (valved muffler + X-pipe + piping) matched for 718 4.0 L layout.

  • Valve controller (for non-PSE cars) to allow manual valve switching — open or closed mode depending on driving situation.

  • Mounting hardware, gaskets and all necessary components for direct-fit installation.

  • Exhaust tips (finish/style options) and instruction sheet for install — system designed for plug-and-play installation.

Product Specs

  • Material: Mandrel-bent T304L stainless steel tubing, precision welded for strength and heat resilience. 

  • Tubing / Flow Path: Uses a custom X-pipe to merge exhaust flow for smoother tone and improved flow when valves open; when valves closed, exhaust is routed through a tuned muffler and secondary flow-path for a quieter, refined note. 

  • Weight: Roughly the same as OEM PSE exhaust (no significant weight penalty) when installed. 

  • Valve Operation: Exhaust valves open/close to switch between aggressive and quiet modes; controlled by valve controller (supplied) or factory PSE logic if present. 

  • Warranty: Covered under SOUL’s lifetime warranty for both street and track use.

Product Features

  • Dual-Mode Exhaust Behavior — “Valves closed” for quiet cruising and minimal drone; “valves open” for loud, aggressive, track-worthy tone.

  • Exotic Flat-Six Sound Character — X-pipe design and optimized muffler path yield a high-pitched, smooth exhaust note more in line with GT-era Porsches. 

  • Anti-Drone Design — Even in louder mode, the muffler and internal flow paths are tuned to reduce unwanted resonance and cabin harshness.

  • Bolt-On, OEM-Compatible Installation — No cutting, welding, or fabrication required; direct-fit to existing exhaust layout. 

  • Valve Controller Included — Gives driver flexible control over exhaust sound independent of factory programming. 

  • Track & Street Versatility — Perfect for owners who want a refined exhaust for daily driving but aggressive tone for spirited drives or track days.
