Sounds like an exhaust leak to me.

Just replace all 4 and you should be ready to go. Manifold to head, turbo to manifold, o2 housing to turbo and downpipe to o2 housing If one is bad the others are on their last leg therefore go ahead and replace them all.

Check the manifold for cracks too. They are very common with these stock cast manifolds. If it is I recommend picking up an fp race mani (Don't mess with any of the tubular ebay junk).
