Extremely Loud Rheem Power Vent Natural Gas Hot Water Heater

I just had a Rheem Power Vent (43V50E2) installed and the sound from the PVC exhaust is extremely loud. The fan sounds like a hair dryer as I suspected but the exhaust is loud enough where it is audible across the street in my neighbor's yard. It appears to be 2.5" PCV piping to a 45" elbow at the end. Would a 3" adapter with 90 degree elbow muffle the sound? I have attached pictures for reference. What are my options to muffle the sound? A quick google wasn't promising (e.g. extended the pipe near the ground to muffle the sound)

The Rheem install manual (http://www.rheem.com/documents/power...nd-care-manual) shows this install wasn't done up to code as it is right below a window and right near the intake/exhaust pipe (see the vent to the left of the PCV exhaust) for the utility room where the furnace gas water heater is installed. Also, they didn't even put silicone to seal the edge around the exhaust pipe.

I have a power vented water heater (Also a Rheem) and yes, it is a bit loud. They have a fan that incorporates inside air to cool the exhaust gases so they can be vented in PVC. I doubt a 3" pipe would change the sound level much, but I am not a pro in this area. Maybe others might have some better advice.

As for the installation issues, I would wait to see what the inspector says. They did pull a permit right?

Sameting here

Mine sounds like a jet taking off , at wakes up everyone in the house. I think the bearings are going out.
My question is. Can I unplug the motor and just have the pipe connect direct , at seems every time I unplug the motor the heater stops. Is there a way I can bypass that? . Thanks

No, you can not bypass it otherwise it will not draft. Unless you want to kill everybody in the house due to CO poisoning. It is not like a standard water heater where the hot gases rise up a flue.
