Product Description

 

 

The Soul Sport Catalytic Converter Downpipe transforms your 718 Cayman or Boxster’s exhaust flow — replacing the restrictive factory downpipe and cat with a high-flow, mandrel-bent stainless system and a high-flow sport catalyst. The upgrade delivers stronger turbo spool response, more immediate throttle feel, and a deeper, more aggressive exhaust note without sacrificing catalytic efficiency or triggering a check-engine light. Lightweight and bolt-on, it’s a perfect first major exhaust upgrade for performance-minded 718 owners wanting more power and character.

Fitment Notes

  • Built specifically for Porsche 718 Cayman / Boxster (2017 and newer 982 generation).

  • Direct-bolt installation in place of the factory catalytic converter and downpipe — uses existing flanges and mounting points. 

  • Designed to run without triggering a check-engine light (when using the included sport-catalyst setup and factory O₂ sensors). 

  • Because flow is improved, this downpipe plays well with upgraded cat-back exhausts or performance tuning — good for tuned or near-stock builds looking for extra response.

Included

  • One high-flow downpipe assembly, fabricated from mandrel-bent T304L stainless steel with thick-wall tubing.

  • Integrated high-flow sport catalytic converter.

  • New exhaust flange gaskets and hardware to ensure proper sealing.

  • Installation instructions

Product Specs

  • Construction: Mandrel-bent T304L stainless steel downpipe with thick-wall tubing for durability under heat and pressure.

  • Catalyst: High-flow sport catalytic converter, designed to maximize flow while preserving catalytic function. 

  • Weight Savings: ~ 4.7 lbs (≈ 2.1 kg) lighter than factory exhaust components (factory ~22.38 lbs vs downpipe ~17.65 lbs). 

  • Performance Gains: Independent dyno testing shows ~ +14 whp and +24 ft-lbs torque, with improved mid-RPM response and turbo spool.

  • Flow and Sound: Larger-diameter smooth bends and reduced back-pressure allow for stronger turbo sound and a more aggressive exhaust tone while retaining catalytic conversion.

Product Features

  • Improved Turbo Response — Reduced back-pressure and enhanced exhaust flow deliver sharper throttle response and more immediate boost behavior.

  • Power & Torque Gains — Real-world dyno gains across the powerband make the 718 feel stronger and more responsive.

  • More Engaging Exhaust Note — Deepened tone and more pronounced turbo growl with sport-cat setup bring character to the 718’s soundtrack.

  • Maintains Emissions Compliance & Sensors — The sport catalyst and proper integration retain factory emissions function and avoid check-engine light issues.

  • Bolt-On, Reversible Upgrade — No cutting or welding required; installs using original mounting points, and can be reverted to stock if desired.

  • Lightweight & Durable Build — T304L stainless steel construction resists corrosion and heat, while weight savings help improve throttle response and reduce rear load.
