Help with identifying this pipe?
 

Hi guys,

I'm resembling a motor but I can't remember what this pipe is for and where is goes? Possibly part of the rats nest for water/oil/fuel?

Attachment 641077

part of the spilt air pipe. its living up to its name

Thanks but where's the split air pipe? I'm still battling to figure out where it goes..

it goes between the main cat and the back of the intake

Doesn't that pipe have a flange that bolts up to to the intake? Or does this pipe connect to that pipe and the to the exhaust?

That is the center piece that bolts to the bottom of the trans.

Okay, thanks for the help :)
