The COBB 3″ Downpipe! This direct replacement for the factory downpipe features 3″ 304 stainless steel tubing, a 4’5″ diameter high-flow GESi catalytic converter.

WHY?

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.
