Default Does the WRX & STi have a clutch delay valve?

Does the WRX and the STi have a clutch delay valve? It's a valve in the hydraulic clutch line that would delay clutch engagement during sudden applications of the clutch in order to protect driveline components.

edit - I did a search and the 03 and up WRX does seem to have one, but I didn't see anything about the STi, does the STi have the clutch delay valve too?

You are correct that the 03+ WRXs have the valve. I'm not sure about the STi though, but I would assume that is does too.

should be easy enough to determine - look at teh clutch slave cylinder, if it has a hexagonal silver thing attached to it that is the valve. the cylinder itself is painted black.

STi does indeed have one. ATS sends you a GC8 slave to use since you can not use a restrictor of any kind with a multi-plate clutch.
