Congratulations on your buy! And welcome to the forum. That noise could be your air pump's belt...Maybe it is too tight and it is straining the bearing? It could also be the pump itself. Maybe a bearing is going out. But you said it has been partially removed, so is the pump still being driven? If the pump is still being driven and some of the other lines are only partially connected, maybe the other noise you hear is the pumping of air...Not an exhaust leak.

As far as another exhaust noise possibility goes...Do you have a wastegate muffler or straight pipe? If you have a straight pipe, you may be hearing the escaping gases coming out of it. This happens when you start pushing some boost (about 3,000 rpm in my car). It can sound like air escaping under high pressure.
