hey all, im thinking about getting a new BOV, its a 02 impreza wrx everything is stock, i will probably keep it mostly that way, im not into racing or anything, but i do like the sound of a louder BOV. i was wondering what kinds i should be looking into, because i believe the stock ones recirculate the blow-off ? is this essential? or can i just buy any 'ol BOV and stick it on there? I'm new to subaru's , and well cars in general, so keep that in mind, lol i think the only other thing i might do in the near future is put a catback on for some better sound, any thoughts there? i want it not too quiet, but not too loud.
