Copper pipe?

[David1206]

It looks like a copper pipe coming off of the left side of the factory exhaust manifold looking from the front of the car. Does anyone know what this is?

I'm assuming you're talking about this which is the EGR tube as Daniel had said

 

[David1206]

That would be it.

 

[Jackie chan]

What about it?

 

[David1206]

Is it necessary for it to be there?

It can be removed but you will get a CEL. This has been covered before, search.
