Product Description

 

 

The Soul Performance Valved Exhaust System for the Porsche 718 Boxster and Cayman (2017+) is a premium direct-fit exhaust upgrade engineered to deliver a refined yet aggressive exhaust tone with the flexibility of valve-controlled sound levels. Constructed from mandrel-bent T304L stainless steel and designed around a performance-oriented muffler architecture, this system maintains a calm, drone-free cabin experience with the valves closed while offering a significantly fuller, sportier tone when the valves open. It pairs effectively with upgraded downpipes for a more robust exhaust character without overpowering resonance, and includes necessary valve control hardware for vehicles without Porsche Sport Exhaust (PSE). Designed for both street driving and spirited use, it’s an ideal balance of everyday comfort and enthusiast-level sound performance.

  • Fits Porsche 718 Boxster / Cayman models (2017–present). 

  • Direct bolt-on installation using factory exhaust mounting points; no cutting or welding required.
