Catted / Catless Performance Downpipes with Heat Shields - McLaren 720S

Upgrade the exhaust performance of your McLaren 720S with these Catted / Catless Performance Downpipes with Integrated Heat Shields. Designed for enthusiasts seeking improved exhaust flow, a more aggressive exhaust note, and performance-oriented construction, these downpipes offer two configuration options to suit different exhaust requirements.

Available in both Catted and Catless configurations, the downpipes are designed to reduce exhaust restrictions and improve the flow of exhaust gases through the turbocharged engine's exhaust system. The catted configuration incorporates high-performance catalytic converters, while the catless configuration eliminates catalytic converters for a less restrictive exhaust path.

Both configurations feature integrated heat shielding designed to help reduce radiant heat exposure to surrounding components. The protective thermal barriers provide an additional layer of heat management around the downpipe assemblies, making them suitable for performance-focused exhaust applications.

Designed specifically for the McLaren 720S, these performance downpipes offer a direct-fit exhaust upgrade for compatible configurations. Whether paired with a factory exhaust arrangement or a compatible aftermarket performance exhaust system, they provide a foundation for a more distinctive exhaust sound and improved exhaust flow characteristics.

Configuration Options

• Catted Downpipes: Equipped with high-performance catalytic converters designed to improve exhaust flow while retaining a catalytic converter configuration. This option provides a more refined exhaust sound compared with the catless alternative.
• Catless Downpipes: Designed without catalytic converters to provide a less restrictive exhaust path. This configuration produces a louder, more aggressive exhaust note and is intended for applications where its use is legally permitted.

Configuration Note: Select either the Catted or Catless configuration according to your exhaust requirements and applicable local regulations. The two configurations have different exhaust flow, sound, and emissions characteristics.

Package Includes

• Performance Downpipe Assemblies: Catted or Catless downpipes according to the selected configuration, featuring integrated thermal heat shielding.
• Installation Hardware: Necessary installation hardware as described in the supplied product specifications.

Features

• High-Flow Performance Design: Engineered to improve exhaust gas movement and reduce restrictions within the McLaren 720S exhaust system.
• Catted & Catless Configurations: Two available downpipe configurations provide flexibility between a catalytic converter-equipped exhaust arrangement and a less restrictive catless design.
• Integrated Thermal Heat Shields: Protective heat shielding helps reduce radiant exhaust heat exposure to surrounding engine bay components.
• Performance Catalytic Converter Option: The catted configuration incorporates high-performance catalytic converters designed to balance exhaust flow with a more refined sound profile.
• Less Restrictive Catless Option: The catless configuration removes catalytic converter restrictions from the downpipe section for improved exhaust flow characteristics.
• Enhanced Exhaust Sound: Designed to produce a more pronounced exhaust note compared with the factory configuration, with sound characteristics varying between Catted and Catless options.
• Refined Catted Exhaust Tone: The catted configuration provides a more controlled exhaust sound while introducing additional performance-oriented exhaust character.
• Aggressive Catless Exhaust Sound: The catless configuration creates a louder, deeper, and more pronounced exhaust note for compatible performance applications.
• Performance-Oriented Construction: Designed to withstand demanding exhaust operating temperatures while supporting reliable exhaust gas flow.
• Thermal Management: Integrated shielding provides protection against radiant heat exposure around the downpipe installation area.
• Vehicle-Specific Design: Developed for the McLaren 720S exhaust configuration rather than universal automotive applications.
• Direct-Fit Configuration: Designed to integrate with compatible McLaren 720S exhaust connections without additional exhaust fabrication according to the supplied specifications.

Vehicle Fitment

• Make: McLaren
• Model: McLaren 720S
• Application: Performance Exhaust Downpipes
• Available Configurations: Catted / Catless

Fitment Note: These performance downpipes are described for the McLaren 720S. Confirm the vehicle's exact model year, factory exhaust configuration, and connection compatibility before ordering.

Exhaust Sound & Performance Benefits

The Catted / Catless Performance Downpipes are designed to improve exhaust gas flow by reducing restrictions in the original downpipe configuration. The high-flow design supports more efficient exhaust movement through the turbocharged exhaust system.

The Catted configuration uses high-performance catalytic converters, providing an exhaust upgrade that retains catalytic converter functionality while introducing a more pronounced exhaust note.

The Catless configuration offers a less restrictive exhaust arrangement without catalytic converters, producing a louder and more aggressive sound for applications where this configuration is permitted.

Both configurations incorporate thermal heat shielding intended to reduce radiant heat exposure to nearby components. Actual changes in horsepower, torque, throttle response, and exhaust sound depend on the vehicle's configuration, engine calibration, and supporting exhaust components.

Installation

The Performance Downpipes with Integrated Heat Shields are designed for direct-fit installation on compatible McLaren 720S exhaust configurations.

According to the supplied specifications, the system includes the necessary installation hardware and is intended to fit without additional modifications to compatible exhaust connections.

Professional installation is recommended to ensure proper exhaust alignment, secure connections, and appropriate clearance around the integrated heat shields.

Before installation, confirm the selected Catted or Catless configuration, vehicle compatibility, and applicable local emissions requirements.

Emissions & Legal Considerations

Catted Configuration: The presence of high-performance catalytic converters does not automatically establish compliance with all emissions regulations. Road-use legality depends on the applicable jurisdiction and relevant product certification.

Catless Configuration: Removing catalytic converters may violate emissions regulations and can make a vehicle unsuitable for public-road use in certain jurisdictions. Verify applicable laws before purchasing or installing this configuration.
