Hey guys just got my fiesta st on Thursday and am trying to decide on some sort of exhaust. I'm having a shop make one and dose anyone know the diameter of the stock exhaust? This thing is wayyyy to quiet for me. Lol thanks!

2.17 inches
Its in your supplemental, or you could have done a quick google search. A whole thread just for this, come on man....

I was going to type just a single word... "tiny" LOL

So after the downpipe the exhaust spilt into dual 2.17 pipes...isn't that 4 inches of pipping for air to go down?? How big of an exhaust does a car with such a tiny turbo need???

Its 1, not dual. dual tips but not dual exhaust. Its 1 tube going from to turbo all the way to the back, thru cat. resonator and muffler with dual tips.
