I did it for a few reasons,

The looks, these things look so great, I will post a few more images very impressive.

Smoother flow, the flex like will certainly slow down flow, trap gunk in the folds (although those fins probably radiate quite a bit of heat)

Less chance of leaks, no slide on this adapter over that adapter

All new parts, no reusing clamps and chopping up the Subaru hoses. (new gates hoses and claps are only like $30) but it all adds up.

Is it a luxury? yes, but it really cleans up the front of the car.
