So i have a blue dot. It has a 18.8 ground joint. As of now it has a 12 hole diffuser with a bushing on it. I plan on buying a inline from ssfg. Drag wise will i be okay if I keep the diffy i have a buy the 14.5 inline. Or should i just go ahead and up my diffy to a 18.8 and also purchase the 18.8 inline? I thought about this the other day. Better ask and see what you guys say, before i drop the money. thanks
