Replacing intercooler

[Curtis]

I have a 1999 Subaru Impreza turbo 2000, the intercooler has a lot of bent fins so I’ve bought a replacement. Everything lines up the same on the new one except there’s one pipe missing and I’m not sure if it’s important or if I can just blank it off. 
the front right pipe looks the same but it doesn’t have a spot for the smaller tube to go onto it like the original, is that a problem?

the pipe is for the blowoff valve and yes you'll need it, looks like its for a a turbosmart style one, normaly they have an adaptor that gets bolted on, but this looks like it has a perminent fixed one.

 

this is the adaptor,
