Just got my 2014 Mazda 3 back from the dealer yesterday after replacing my CV joint and both front wheel bearings (was around $1000) and now I am noticing a rattling sound from my exhaust!

The last thing I need is to spend more money on repairs.. The sound is coming from the rear right side and seems to be louder inside the cabin than outside. While outside of the car the sound sounds more like its coming from around the rear right wheel than straight from the end of my exhaust. Only can notice the sound at idle and comes in waves or rattling sometimes.

Has anyone had a similar issue or have a potential fix or diagnosis, please let me know...

You’re probably going to have to get on the ground and take a look under the car in order to diagnose it without having to spend money. There are a lot of things it could be. A loose heat shield, road debris, broken muffler hanger. The only way to know is going to be to look for something loose.
