Re: Bing 15-2.5 diffuser?
right... I am asking because I am using a 2.22 diffuser on my drilled out bing 12 and was curious if I could get more flow from the bing 15 diffuser(2.5?). Anyone know anything about this? I am assuming a 2.5 diffuser is bigger than a 2.22 diffuser which is much larger than the 2.17 diffuser. Thanks
