Cat Replacement Pipes McLaren 570 570S Sport Exhaust Exhaust Stainless Steel

Cat Replacement Pipes (also known as Cat-Bypass or Test Pipes) for the McLaren 570S are one of the most effective ways to unlock the acoustic potential of the 3.8L Twin-Turbo V8. Because the factory catalytic converters act as massive heat sinks and sound mufflers, replacing them with stainless steel pipes significantly improves exhaust flow and reduces engine bay temperatures.

1. Technical Specifications

For the McLaren 570S, these pipes are typically designed as “Downpipes” that connect the turbos to the rear exhaust section.

• Material: T304 Aircraft Grade Stainless Steel (1.5mm to 2.0mm wall thickness).

• Design: CNC Mandrel-bent for smooth airflow; usually $3\text{ inch}$ ($76\text{mm}$) diameter.

• Heat Management: High-quality pipes come Ceramic Coated or feature an Integrated Heat Shield (Inconel or Stainless) to protect the sensitive wiring and carbon fiber components in the McLaren engine bay.
