Squeaky Sound When Hitting Bumps

I've had this problem for a while now.
I noticed when I hit a bump, there is a sqeak noise like sound exactly like an old mattress spring.
It happened shortly after I placed in my U-Bend Delete so I narrowed it down to the exhaust. I though it was my resonator cover and had it removed (the cover). No luck. When I move an exhaust tip around there is no noise. It only occurs when I hit a bump.
Could it be the suspension? Never had suspension problems on my cars before so I can't tell.
Got 110k with stock suspension and exhaust.

is the sound coming from the front? If so grease or replace your ball joints. I had the came thing happen with a mustang I had, I replace the struts and mounts and still had the same problem.... Sounded like someone was jumping on an old mattress. Then I bought a grease gun and greased the ball joints and I never heard that sound again.

Truthfully, I don't know where the source of the noise is since I’m inside. It seems to be originating from the in the center but more on the rear passenger side. I tried pushing the car up and down from outside but I hear nothing.
I'll look into greasing the ball joints.
Maybe I have two issues. Seems when I hit bumps, I hear something knocking under the car. Like the exhaust is bouncing around and hitting the undercarriage. It did it just now while I was in a parking lot going 4-5 mph.

It sounds exactly like a broken bar swinging from side to side, hitting itself. A swaybar breaking known to break?! Wowsers. I'll check under the car tomorrow and report.

There have been a couple of swaybars that broke over on ClubGP. I've notice that they were from "cold" states, that use road salt.

Not sure if I reported this already but I found out where the squeaky sound was comming from.
One of the exhaust tips is leaning over too much and hitting the rear ground effects when I hit a bump. I can replicate it by swinging the exhaust back and forth.
Midas says its because the U-bend delete hanger I have is not exactly perfect and is causing one tip to move over a little too far.
They tried to fix it for free but they messed it up and shortening its life by moving it around a lot. Now I can hear more drone at lower RPM like its going bad.
I'm looking into a nice, quiet sounding exhaust (EDIT: quiet in the inside cabin. It can sound like whatever outside.) . Maybe just a stock system with corsa tips.
Thoughts?

Yea, didn't make all that much sense to me either. He showed me and I kind and he is sort of correct. The pipe could have just been heated up and bent.
Not sure how I can fix the reverbing issue. Use newer rubber hangers at the rear?

I would say that it is the rubber hangars in the rear. The U-bend hangar is pretty far away from the tips.
