COBB Tuning GESi Catted 3″ Downpipe – Ford Focus RS 2016-2018
- 4.5″ High Flow GESi Catalytic Converter
- Flex Joint allows for movement and heat expansion without risk of damage or leaks during aggressive driving
- Compatible with OEM turbo and cat-back or COBB 3″ Stainless Steel Cat-Back Exhaust
This will probably be the only downpipe you will ever need for your Focus RS. It is compatible with our OTS Stage2+ maps but will also be the perfect starting point for big power builds with upgraded turbo’s!
**Important Note** – Due to the significant restriction found in the factory turbine-housing on all stock Focus RS turbo configurations. There will be no consistent power gains between stage2 and stage2+ maps and parts. Therefore the main focus for purchasing and installing the COBB Downpipe or Stage2+ Package is for the more improved exhaust note but will also effectively prepare the car to make optimal power for those that desire to upgrade the factory turbo system.
