I see some people changing there Jet and HF dust collectors over to 6" ducting to improve its performance and had a question regarding the output to the bag/filter. It looks like most have a 5" outlet and hose to the bag/filter part. How does that affect the change of the inlet to 6"? It would seem that if you changed the inlet to 6" then the outlet would need up sized as well. I do realize its a much shorter run and maybe thats why it would be o.k. Any thoughts?
