[QUOTE="VereChronicus, post: 1909974, member: 565864"] The cool thing about the ports is that you can seal them up anytime you like. At any big fabrics store, you can find "SEAT CUSHION FOAM". It comes in different sized blocks. Get one big enough to fit about 5" into your vent or ports. Stuff it in there and the port is now sealed. The volume taken up by the port foam is pretty tiny, so it is nearly the same internal volume as the sealed system. [/QUOTE]
