Both of those pipes are 2". I see no 3".
If they are 3", then either
A: they increased to 3" way to far down the line.
B: They used a reducer on a horizontal plane. If the reducer is on a horizontal plane, then the condensate will eventually fill the 3", untill it acts like 2" pipe. All reducers/increasers should be vertical to prevent this (unless it's NOT a concentric reducer).
Either way, it's wrong. Please, post pictures of where the flue exits the building, and more pictures of the furnace closet.
The problem, is a 2" pipe does not handle the ammount of heat coming out of a 90k btu furnace. It also does not supply enough combustion air. So both pipes have to be 3". If you read the install manual, under "direct venting", it shows a 90k btu furnace MUST USE 3" PIPES. both of them. Doing otherwise could cause pre-mature inducer and heat exchanger failure, both of which would not be covered under warranty due to improper install.
See the two fittings close to the furnace, and how they make sharp turns? See the fitting up above the door header, how it has a "neck" between where the pipe goes into? The one with the neck is correct. The two next to the furnace are wrong, as they cause restriction from the sharp turn.
The IAQ mod needs to be moved also.
Show me more pictures. focus on the flues. Post a picture of the condensate pump. Other side of furnace also.
Please post model (not serial) #'s of all equitment. Furnace, indoor coil, and outdoor unit. I suspect other problems, but will ellaborate after more information.
