I went into U-Haul to install a Class 1 hitch - 1.25". You can find it here:

There's two options. I went with the Sportframe 1 1/4 Inch Rec (2000 max lbs part number: 24917). I had U-Haul install it for me because I know nothing about working on cars and don't have time to figure it out. It took them about an hour. Once they were done and I turned on the car, I immediately noticed my exhaust was significantly louder. Not in a bad way either... The sound was a lot lower. Driving it off, I could hear the majority of the difference at 2-3k RPM. It was loud!! Like my car was rumbling, loud. Like an aftermarket exhaust loud. It definitely does not sound like anything loose that is coming into contact with something else. I got home and checked below the car to see what I could find.. and nothing seemed like a problem to my untrained eye. The muffler and all the pipes seem to have good clearnage from the hitch receiver.
Anyway, does anyone know what's going on?? I really like the new sound, but am worried what might have caused the change could be a sign of trouble.
The full install instructions are on the linked site, but here's the main part:
1. Lower exhaust at the rubber isolator on both sides of the exhaust. Spraying a lubricant or soapy water on the metal hanger rod and the rubber isolator helps
removal.
2. Remove rubber plugs from the bottom of the vehicle.
3. Using forward most hole in vehicle and supplied bolt leader, insert 7/16” bolt and spacer block into frame as show in figure 1.
4. Raise hitch into place.
5. Attach conical washers and nuts, finger tighten.
6. Torque all hardware to torque specification below.
7. Raise exhaust and reattach rubber isolators.
