You might want to go to the Fiesta ST forums and search for threads on the item you are working with. The various modifications to the 1.6 turbo might allow you to use the downpipe you have as part of several other upgrades. But, there are many complex mods for the Fiesta ST. You will need to give careful consideration to what you want to achieve and the quickly spiraling costs associated with many changes.
