McLaren 765LT / 750S Performance Catless Downpipes with Heat Shield

Upgrade your McLaren 765LT or 750S with Performance Catless Downpipes designed to improve exhaust flow, turbo response, and exhaust sound. Engineered for the 4.0L twin-turbocharged V8, these downpipes replace the factory catalytic converters with a catless configuration intended for performance-focused driving.

Constructed from T304 stainless steel as standard, with full titanium available as an optional material, these downpipes feature mandrel-bent tubing, TIG-welded construction, CNC-machined flanges, and integrated thermal heat shielding or an optional ceramic-coated finish. Factory O2 sensor port provisions support integration with compatible exhaust configurations.

Installation

These downpipes are designed for compatible McLaren exhaust configurations. Professional installation is recommended to ensure proper alignment, secure connections, sensor installation, and adequate clearance from surrounding components.

ECU tuning is strongly recommended to help optimize the setup and address potential check-engine lights associated with the catless configuration.

Important: Intended for off-road and racing use only where permitted by law. Removing catalytic converters may violate local emissions regulations and make the vehicle unsuitable for public-road use. Verify applicable regulations before purchasing or installing.

Care Guide

• Allow the Exhaust to Cool: Always allow the exhaust system and heat shields to cool completely before cleaning, inspection, or maintenance. Exhaust components can remain extremely hot after driving.
• Regular Cleaning: Clean accessible exterior surfaces with a soft microfiber cloth and a suitable automotive cleaner. Avoid abrasive pads, harsh chemicals, and aggressive polishing products that could damage the metal finish or protective coating.
• Inspect Heat Shields: Periodically check heat shields, mounting points, clamps, and fasteners for looseness or visible damage. Have any issues inspected by a qualified technician.
• Check for Leaks: Have exhaust connections and joints inspected periodically for signs of exhaust leaks, unusual noises, or damaged seals.
• Protect the Finish: Avoid corrosive cleaning agents and prolonged contact with road salts or other contaminants. Use cleaning products appropriate for the installed material and any ceramic coating.
• Professional Maintenance: Have the system inspected after installation and following intensive track use to help maintain secure mounting and reliable operation.
