ok, sounds good. it will have a good sound with that large diameter pipe all the way back. my 4.3 trucks always have the bendy straw y pipe.

and in the end the only one that would give you trouble is that butt joint where the two pipes join, the rest are slip joints so even tacks would keep them together.
