Cobb Tuning GESI Catted 3" Downpipe for 2016+ Ford Focus RS
The COBB GESi Catted 3" Downpipe is a direct replacement for the Focus RS's factory downpipe. It features 3" 304 stainless steel tubing, a 4.5" diameter GESi catalytic converter, and high quality flanges on either end. A replacement Ford OE clamp is included for the flange at the cat-back junction. **Tuning is Required**
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.
