You will need two separate duct runs if you want to use two fans. I tried the same thing once and the higher powered fan was pulling air through the slower one. If the rooms are connected you could use passive air flow by putting some 8" holes in the shared wall. Then you could put the other duct run right by the first one. Reading this post helped me alot as well: https://www.icmag.com/ic/showthread.php?t=100823&highlight=air+flow

Anyone else venting multiple rooms thru 1 or 2 hole in the wall ????????
I was thinking of building a 5ft by 5ft box in the attic. 3 rooms venting into the box via 8 inch duct. the box would be connected to the wall with the 2 - 7 inch vents on the interior of the box and the whole thing sealed to create a mini room .
Will the box make a difference, it will be like a mini lung room........ i think lol

I don't know if it is a option for you but, if you put the fan after the Wye it would draw equally from each duct assuming the same duct length and pressure drop. If they are not the same you could install balancing dampers to adjust airflow. You might be able to balance the flow from the outlets but you will have a great airflow loss. In a previous life I balanced airflow professionally and two fans venting into one outlet never worked. It never stopped an engineer from designing it that way though.
You have an 8" venting into a 7",that is a loss. Two 8" pipes should go into at least a 10", 12" would be better. Also if one fan is not running the exhaust will feed back into the other room

Ok
For those people that care ( lol )
You cant really connect 2 duct runs to 1 outlet with a Y connector without loosing a shit load of air flow
I tried everythin, same scrubbers, same fans, same length duct, back draft shutters but when you connect them to one outlet thru a Y connector you loose 80% of the extract in the rooms
Y connectors suck ass for extracting 2 rooms with 2 fans.
I ended up drilling 2 8" holes and have one room running to each, and my rooms are now perfectly cooled
Thanks for the advise Chaos and whyme
