Product Description

 

 

Fabspeed’s 991 Turbo Sport Catalytic Converters swap out the factory catalytic units for high-flow 200-cell HJS “Sport Cats,” cutting back-pressure and boosting exhaust flow to enhance throttle response, turbo efficiency, and overall performance — without sacrificing emissions-sensor compatibility or triggering a check-engine light. The result is sharper turbo spool, stronger mid-range punch, and a more aggressive exhaust note, while retaining a bolt-on installation and usable drivability. It’s an ideal upgrade for owners seeking better performance and sound with minimal compromise.

Fitment Notes

  • Designed for Porsche 991 Turbo & 991 Turbo S models — all 2013 through 2016 variants. 

  • Direct bolt-on replacement for the stock catalytic converter or in place of factory catalytic converter/back-box assembly — no fabrication or cutting required. 

  • Includes integrated O₂-sensor bung(s), ensuring compatibility with the factory engine management and avoiding “check-engine” triggers when installed properly.

Included

  • Pair (full set) of high-flow “Sport” catalytic converters (200-cell HJS cats), configured for direct fitment to 991 Turbo exhaust plumbing. 

  • Mandrel-bent stainless-steel housings and flanges for durability and optimized flow. 

  • All necessary hardware and O₂-sensor provisions for bolt-on installation — includes gaskets, clamps, and sensor bungs.

Product Specs

  • Material: 14–16 gauge T304L stainless steel housings and flanges for corrosion and heat resistance. 

  • Catalytic Core: 200-cell sport catalytic converter (HJS), high-flow design optimized for performance exhaust flow. 

  • O₂ Sensor Provision: Integrated bung(s) for factory O₂ sensors — maintains ECU compatibility and avoids CEL when installed with stock sensors. 

  • Fitment: Direct bolt-on replacement for 991 Turbo / Turbo S (2013-2016). 

  • Exhaust Flow Efficiency: Sport cats flow approximately 92–95% of a straight-pipe setup while retaining catalytic function.

  • Back-Pressure Reduction: Designed to reduce exhaust restriction compared to OEM cats, leading to improved turbo response and reduced turbo lag.

  • Durability: Stainless steel construction and high-quality catalyzer build designed to withstand heat and stress typical of turbocharged driving.

Product Features

  • Enhanced Turbo Response & Driveability — By lowering exhaust back-pressure and improving flow, the turbo(s) can spool faster and maintain stronger boost, giving more immediate throttle response and better mid-range power delivery.

  • Aggressive Exhaust Sound with Functionality — The sport catalytic converters allow a more free-flowing exhaust note with richer tone, while still using catalytic chemistry to reduce emissions and avoid sensor issues.

  • Bolt-On, OEM-Friendly Fitment — Because of integrated O₂ sensor bungs and direct-fit design, this upgrade installs cleanly with factory exhaust mount points — no cutting, welding or custom fabrication required.

  • Emissions-Sensor Safe (versus full straight-pipe) — Unlike cat-bypass/sport-pipe kits, these sport cats preserve emissions monitoring components, minimizing the risk of check-engine lights when done properly.

  • Balanced Performance & Longevity — The combination of high-flow catalyst and stainless-steel housing delivers a blend of performance, sound, and durability — making this a solid baseline upgrade for street, track-day, or performance builds.

  • Solid Base for Further Upgrades — Installing higher-flow cats reduces restrictions and primes the exhaust system for future bolt-on upgrades (like valved cat-back or X-pipe systems), maximizing gains down the build path.
