The 2016 to 2017 Focus RS and its 2.3L turbocharged EcoBoost engine has a whole lot of potential, and one of the easier ways to unlock some of that potential is with MBRP's 3" Catted Downpipe. Constructed from mandrel-bent 3" 304 stainless steel tubing, this heavy-duty catted downpipe replaces your factory downpipe and OEM catalytic converter, removing factory restrictions and improving flow for maximum power output. This MBRP Catted Downpipe is capable of increasing flow by 46%!
