If so is recirculation better than vent to atmosphere? Is there any difference with an aftermarket bov on a stock sti compared to a stage 2 sti or stage 3? I love my subie and i dont wanna hurt her =/

If you want your car to run properly full recirc is the best way to go. If the stock BPV isn't leaking don't change it. Save the money and buy something that will improve performance and not just make noise.
