Best Subaru Impreza Exhaust Sound 2.0L 2.5L?

[Charles7000]

I saw this video comparing most Subaru Impreza exhaust but still cannot decide.

 

 

Any tips on the best Subaru Impreza exhaust? hp? sound?

I would appreciate hearing from those that already upgraded their exhaust.

Think I like the MBRP Axle-Back but could I live with it as a daily. The 2.0 liter sounds harsher than the 2.5, has more of a burble in most cases.
