RENNVOX McLaren 720S Downpipes With 

200 Cell 3-Core Catalytic Converter

Unlock greater performance from the McLaren 720S with RENNVOX Downpipes With 200 Cell 3-Core Catalytic Converter, engineered specifically for the 4.0-litre twin-turbocharged V8.

Designed to reduce exhaust restriction compared with the factory catalytic converter assemblies, the RENNVOX downpipes improve exhaust gas flow from the turbochargers. The result is a more responsive exhaust system designed to support increased performance, sharper response and a more aggressive exhaust note.

At the heart of each downpipe is a high-flow 200-cell, three-core catalyst configuration. The multi-core design provides increased catalyst capacity and surface area while maintaining high exhaust flow, making it particularly suited to the extreme exhaust temperatures and gas volumes produced by high-performance and tuned McLaren 720S applications.

This three-core construction is designed with both performance and endurance in mind. By distributing exhaust flow and thermal load across multiple catalyst cores, the system is engineered to provide greater thermal capacity and durability under sustained high-load driving while retaining the flow advantages expected from a performance 200-cell downpipe.

When combined with a RENNVOX performance exhaust or other compatible exhaust system, the downpipes form part of a complete high-flow exhaust solution for owners looking to extract more from the 720S while retaining high-flow catalytic converters.

Why Upgrade the McLaren 720S Downpipes?

The factory downpipes and catalytic converters must balance emissions, noise, packaging and performance requirements. For modified and performance-focused vehicles, reducing restriction immediately downstream of the turbochargers can improve the efficiency of the exhaust path.

The RENNVOX Downpipes With 200 Cell 3-Core Catalytic Converter provide a freer-flowing alternative engineered specifically around the performance demands of the McLaren 720S.

FAQ

What does the three-core catalyst design do?

The three-core configuration uses multiple 200-cell catalyst cores to provide increased catalyst capacity and surface area while maintaining high exhaust flow. The design also distributes thermal load across the catalyst assembly, supporting increased performance and endurance in demanding high-temperature applications.

Are these downpipes designed for tuned McLaren 720S vehicles?

Yes. Their high-flow construction and increased thermal capacity make them particularly suited to performance and tuned applications. ECU calibration requirements will depend on the vehicle's individual configuration and other modifications.

Will the downpipes change the exhaust sound?

Yes. High-flow 200-cell downpipes typically produce a stronger and more aggressive exhaust character by reducing the restriction of the factory catalytic converter assemblies. The final sound will depend on the remainder of the exhaust system.

Can these downpipes be used with a RENNVOX exhaust system?

Yes. They are designed to complement compatible RENNVOX McLaren 720S exhaust components and can form part of a complete high-flow exhaust system.

Will ECU tuning be required?

ECU calibration requirements can vary depending on the vehicle, software version, exhaust configuration and other modifications. For performance-focused applications, appropriate ECU calibration may also allow the vehicle to take greater advantage of the increased exhaust flow.

Are 200-cell catalytic converters road legal?

Road-use and emissions requirements vary by jurisdiction. Installation of aftermarket catalytic converters or other exhaust modifications may affect emissions compliance and road legality. Owners should confirm applicable local requirements before installation or road use.
