Hey everyone, just looking for a few good ideas...
I have the HF DC and it comes with a Y that has 4" inlets. However, without the Y the inlet is 5". So, I am pitching the Y and definitely going to run main lines that are at least 5". My question is this: Is there any advantage to running main lines that are larger, such as 6" or 7", when I would have to reduce down to 5" back at the collector?
