Product Description

 

 

Upgrade your 600LT’s exhaust system with Fabspeed’s Sport Catalytic Converters — high-flow, race-inspired catalysts that replace the restrictive factory cats and let your twin-turbo V8 exhale freely. Engineered using premium 200-cell HJS German catalysts housed in T304L stainless steel, this system reduces back-pressure and improves exhaust flow. The result: sharper throttle response, faster turbo spool, more midrange punch — and a deeper, more aggressive exhaust note worthy of a hypercar. With thermal-blanket protection built in and dyno-tuned flow optimization, this upgrade gives you high-performance gains while maintaining structural integrity under extreme heat.

Fitment Notes

  • Compatible with all 2019–2021 McLaren 600LT (Coupes / Spider). 

  • Direct replacement for the original catalytic converters — designed to mate to factory exhaust manifolds and downstream piping without major custom fabrication. 

  • Because this is a high-flow sport-cat system, it is optimized for performance and may not be emissions-compliant in all jurisdictions — check local laws before installation.

Included

  • Pair of high-flow sport catalytic converters (left + right banks) with HJS 200-cell cells, pre-assembled in T304L stainless housings

  • Heavy-duty thermal blankets (“military-spec” heat insulation) covering the catalysts — rated for extreme thermal loads. 

  • All necessary flanges and hardware required for bolt-on installation to existing exhaust components.

Product Specs

  • Catalyst type: HJS German 200-cell high-flow catalytic converters — designed for high flow while retaining catalytic function. 

  • Construction: Mandrel-bent T304L stainless steel housings for durability, heat resistance, and longevity. 

  • Heat protection: Included thermal blankets rated to high temperatures — ensures exhaust heat stays contained, preserving exhaust velocity and protecting nearby components. 

  • Flow improvement: Engineered to significantly reduce back-pressure compared with OEM cats — yielding quicker turbo spool and freer exhaust flow.

Product Features

  • High-Flow Catalysts with Real-World Performance: The HJS 200-cell units flow nearly as freely as a cat-bypass pipe while still performing catalytic function — delivering improved power delivery and throttle response without fully deleting emissions hardware or triggering a CEL.

  • Sharper Throttle Response & Faster Turbo Spool: With less restriction after the turbo, exhaust gases evacuate more efficiently — reducing turbo lag and improving overall engine responsiveness under load.

  • Aggressive, Hypercar-Worthy Exhaust Tone: Freer flow and a more open exhaust path liberate a deeper, richer exhaust note — giving your 600 LT a more dramatic, sporty sound character. 

  • Durable, Heat-Resistant Construction: T304L stainless housing and included heat blankets protect against thermal stress and corrosion, ensuring longevity even under track use or repeated high-temperature cycles.

  • Bolt-On Installation for OEM-Level Fitment: Designed to connect directly to factory exhaust manifolds and piping — no cutting or welding required when installed correctly. 

  • Track & Performance Build Friendly: Ideal for tuned builds, track-day use, or owners seeking maximum performance from their 600 LT — while still offering a viable upgrade path if cats need to be retained for inspection or registration in less restrictive regions.
