Its all about gross air flow and resistance in a certain size pipe. If you run a smaller IC pipe, you have less empty space to fill so you reach full boost sooner, BUT you can't flow as much air through it. On the other hand if you run a larger diameter IC pipe, you can push more overall volume through it, but since there is more void to fill, it takes longer to reach full boost.

for a street car with up to 400whp 2'' is fine.

Eh, I think 2'' is a little small, 2.5'' is a lot more suitable imo.
