I have a 94 IDI turbo,I have a full 3" exhaust with no muffler,it sounds good until higher rpm then it starts to sound like a glass pack,I hate that sound,if I use a 4" complete from downpipe back will that go away? It seems that with a 3" DP and the rest 3" it may still be restricted,any advice?

I've got 4" from the downpipe back, but I've still got to replace the stock downpipe (I know...) I get the glass pack sound around 2500, which is a little better than before the 4". I would have to think that a larger downpipe would cut it down some more.
