So I just installed a Dynomax catback 39434 on my 09 Mustang 2 weeks ago. Well I am getting some rattling inside the car and it seems almost like it's being caused by the hangers that came with the dynomax kit. Has anyone else that installed this kit had any issues with their kit rattling?

Check at the back and see if your hangers are tapping on the metal beam in the rear bumper. It may just be an adjustment. I had a similar thing on my 2006 and one side was tapping that beam.

Nope not even close to the beam, I am thinking it's because the mounts that came with the exhaust system are solid rubber chunk with a hole in the center unlike the oem which is more hollow looking.
