2.5" downpipe to full 2.5" ISR exhaust?

Looking to boost soon with a T25 turbo. I'm thinking of getting a custom 2.5" downpipe made to connect to a 2.5" ISR exhaust. Has anyone done this before? I'd rather go 3" stainless but that is out of the budget right now so full 2.5" it is.

What do you expect the response to be? You already started a useless thread about exhausts. Who cares if someone has done it before, if you are too cheap to do it right, go ahead and get a custom 2.5" downpipe made and report your results.
