3.0" Performance Downpipe

The Extreme Turbo Systems (ETS) Focus RS Downpipe is engineered to optimize exhaust flow and performance for the Ford Focus RS Mk3. Featuring a true 3.0" diameter, this downpipe is designed to significantly reduce back-pressure, promoting improved turbo spool and overall engine efficiency. For seamless installation and compatibility, this downpipe is designed as a direct fit for Extreme Turbo Systems' own Catback exhaust systems. While other aftermarket 3.0" exhaust systems may work, users will need to modify them by cutting off a restrictive v-band connection to ensure proper integration. This downpipe is compatible with the 2016, 2017, and 2018 Ford Focus RS models. It is crucial to note that this downpipe is intended to connect to aftermarket exhaust systems and does not provide a direct fit to the factory exhaust. As a performance-oriented component, while specific ECU tuning requirements are not explicitly stated for this particular downpipe in the provided evidence, it is common for significant exhaust modifications on turbocharged vehicles like the Focus RS to benefit from or require an ECU tune to achieve optimal performance and prevent potential issues.
