A picture would help me understand a lot more mate.
From what I'm getting, your 90° rubber pipe coming from your egr delete to your hard plastic intercooler pipe has split? And you want a new one?
Scrap yard will probably be your cheapest option, then youst cut down where the clip slots in with a hacksaw, the the metal part of the pipe will come off the rubber

Other than that you could get an aftermarket 90° hose but fitting it to the hard plastic intrrcooler pipenwould be a problem.
Hope this helps? Hoggy.
