2005 WRX Y piece
 

Looking to get a new Y piece for a 2005 WRX.

Now is it a case of just get ones of these aftermarket silicon kits, or are the hard pipe sti kits any better, if they fit at all?

Forgive the dumb question, new to Impreza ownership and just wanting to do the basics and no more (think of it as ppp on the cheap :p).
