Product Description

 

 

The Fabspeed McLaren 720S HJS German 200 CPSI Sport Catalytic Converters are a high‑flow performance upgrade engineered to replace the restrictive stock catalytic converters on the 720S. These sport cats use oversized, high‑flow 200‑cell HJS German‑imported catalyst cores to deliver exhaust flow rates equivalent to approximately 93–95% of a straight pipe, dramatically reducing backpressure while still providing catalytic function and avoiding check engine lights in most applications. Hand‑crafted with precision and developed through extensive testing on McLaren platforms, this upgrade improves turbocharger efficiency, enhances throttle response, and produces a more exotic and engaging exhaust tone when paired with supporting exhaust components or tuning. Backed by Fabspeed’s industry reputation for quality and durability, these sport cats are ideal for drivers who want a significant performance edge from their 720S without resorting to fully deleted systems.

Fitment Notes

  • Designed specifically for McLaren 720S (model years 2018 and newer). 

  • Replaces the four OEM catalytic converters with two high‑flow sport catalytic assemblies. 

  • Works in conjunction with factory or aftermarket exhaust systems. 

  • Professional installation recommended to ensure proper fitment and thermal management.

Included

  • Pair of Fabspeed HJS German 200 CPSI Sport Catalytic Converters (left and right banks).

  • Direct‑fit mounting hardware.

  • High‑temperature thermal insulation blankets (helps retain exhaust velocity and protect nearby components).

Product Specs

  • Catalyst Core: 200 CPSI HJS German‑imported tri‑metallic cores designed for high flow with catalytic function. 

  • Construction: Premium stainless steel housings and tubing sized for maximum flow and strength. 

  • Flow Efficiency: ~93–95% of straight‑pipe flow in most applications.

  • Inlet Size: ~5.15″ / 130 mm diameter catalyst bodies (largest that fit the 720S chassis). 

  • Thermal Blankets: Military‑spec heat blankets rated to maintain thermal efficiency under high‑heat conditions.

Product Features

  • High‑flow catalyst design: Reduces backpressure for quicker turbo spool and improved throttle response.

  • HJS German‑imported catalyst cores: World‑class catalyst media that supports high power levels (up to and beyond 1200 HP in many builds) while maintaining emissions scrubbing and minimizing CEL risk. 

  • Large‑diameter construction: Oversized inlet pipes and catalyst bodies maximize exhaust flow and velocity. 

  • Enhanced exhaust tone: Unleashes a more aggressive, exotic sound characteristic compared with factory catalytic converters.

  • Thermal blanket protection: Helps retain heat within the catalytic bodies for optimized exhaust gas velocity and protects adjacent components. 

  • Bolt‑on direct fit: Designed to integrate smoothly with existing exhaust components for straightforward installation.
