Only cons

Subarus engine management does not support blow off valves because it's a MAF based system. The air the factory recirculating valve sends back into the system is already accounted for and fuel is applied accordingly.

There is definitely a pro though!

If the bov has the correct diameter then one could fashion a makeshift adapter with silicone tubing and attach a duck call!

It’d be brilliant if the car quacked after every shift!
