Blow off valve

[droppinbottom]

I have recently added my fmic and after the install I have noticed that I can hear the blow off valve now. I never heard it before. I can hear it mainly when I build a little boost (10psi or so) in the lower rpms. Is this common or do I need to look into something? It is the stock 1g bov.

thanks

Metal piping makes it louder, its normal.
