Unlock more power and a more aggressive exhaust character for your 2021‑on Porsche 911 992 Turbo / Turbo S with Fabspeed’s Sport Catalytic Converters. These high‑flow 200‑cell Catalysts replace the restrictive OEM cats — reducing back‑pressure and allowing the twin‑turbo flat‑six to breathe more freely while preserving catalytic function and avoiding emission‑related errors. The result: quicker turbo spool, stronger mid‑ and upper‑RPM punch, and a deeper, richer exhaust tone with sharper burbles and pops under throttle transitions and decel. This upgrade brings track‑level performance gains while maintaining street usability and OEM‑style emissions compliance (in many markets).
Compatible with all 2021‑present Porsche 992 Turbo / 992 Turbo S, Coupe or Cabriolet.
Designed as a direct‑bolt replacement for OEM catalytic converters — no cutting, welding or major fabrication required.
Works with factory exhaust plumbing and valves; compatible with stock mufflers or aftermarket exhaust systems (including valved options) without triggering check‑engine lights (on US-market cars) due to the use of homologated high‑flow catalysts.
Pair of high‑flow HJS HD 200‑cell catalytic converter assemblies (left + right banks).
Mandrel‑bent T304L stainless‑steel housings, flanges, and all required hardware for direct bolt‑on installation.
Catalyst Media: High‑flow, 200‑cell HJS “Emitec” catalytic cores — OEM‑grade, European‑certified.
Construction: Mandrel‑bent T304L stainless‑steel, using 14‑16 gauge wall thickness for strength, heat resistance and longevity.
Flow Efficiency: Catalysts flow up to 90–93% of a straight‑pipe while maintaining proper emissions scrubbing (as claimed by the manufacturer).
Dyno‑tested Performance Gains: Up to +54.9 wheel horsepower (whp) and +58.9 ft‑lbs of torque (wtq) over stock — significant across the RPM band.
Weight Savings: Estimated ~25 lbs (≈ 11.3 kg) reduction compared with stock catalytic units/muffler combination (depending on outlets/configuration) for improved responsiveness.
Big power & torque gains — without losing the cats: Thanks to high‑flow HJS catalysts, you get major gains in throttle response, mid‑range punch, and high‑end power all while keeping catalytic function intact and avoiding check engine lights (in supported markets).
Sharper turbo response & reduced lag: Lower back‑pressure allows turbochargers to spool faster and harder — giving more immediate boost response under load and better transient performance.
Deeper, more defined exhaust tone: Expect a richer, more aggressive exhaust note with louder spool sounds, deeper burbles, and more pronounced pops/bangs on throttle lift or downshift — dramatically more exotic than stock.
Direct bolt‑on, OEM‑grade fitment: Precision CAD‑scanned and manufactured to OEM tolerances — no cutting, welding, or custom exhaust work needed for installation.
Street‑use friendly yet track capable: Because the system retains catalytic converters with proper emissions functionality (on compliant markets), it balances performance, sound, and day‑to‑day drivability — making it a versatile upgrade whether you commute, cruise, or track.
Durable build quality & long‑term reliability: Stainless‑steel construction + high‑grade HJS catalysts mean this system is built for longevity under high heat, boost, and repeated driving cycles — ideal for high‑performance, turbocharged flat‑six engines.
