Sorry for bumping an old thread... reading through this thread, and the following warranty sheet:
http://fordperformanceracingparts.com/warranty/Select_Parts_Warranty_Statement_2015.pdf
Lists Fiesta ST parts that do not affect warranty/are covered.
But it doesn't list Mountune's CBE.
Ford's site says it's fine:
http://fordperformanceracingparts.com/parts/part_details.asp?PartKeyField=25223
Mountune's site does not:
http://www.mountuneusa.com/mountune-High-Flow-Exhaust-Fiesta-ST-p/2364-cbe-ab.htm
So what's the word?
