3" is the way to go when talking downpipes. The Mishimoto Fiesta ST downpipe is 3" from the turbine outlet flange all the way to the flex pipe. Maximizing flow and reducing backpressure is the key to unlocking potential in any turbocharged vehicle. The reduced backpressure speeds up turbo spool to drop the boost threshold lower in the rev range.
