FI Exhaust 2017–2023 McLaren 720S High-Flow Downpipes

Available in Catless and Sport 200 Cell Versions

Unleash the full potential of your McLaren 720S with FI Exhaust’s precision-engineered High-Flow Downpipes. Designed specifically for the 2017–2023 McLaren 720S, these downpipes dramatically improve exhaust flow, turbo response, and overall performance—transforming your supercar into a sharper, more visceral machine.

Catless (Standard Version)

The Catless Downpipes remove the restrictive factory catalytic converters entirely, eliminating exhaust backpressure for maximum flow and power gains. The result is a significant increase in turbo spool speed, throttle response, and exhaust volume, accompanied by a pure, unfiltered McLaren tone. This version is ideal for vehicles equipped with ECU tuning or those seeking the most aggressive sound and performance characteristics.

Sport 200 Cell Version

The Sport 200 Cell Downpipes feature high-quality metallic catalytic cores with larger cell openings, which maintain strong exhaust flow while ensuring emissions compliance in select regions. Engineered for optimal balance, the 200-cell design provides enhanced torque in the mid-range while freeing up top-end horsepower. Constructed from heat-resistant stainless steel, these downpipes are built to endure extreme track or street use without degradation or wool burn-out issues.
