2015 Mustang doesn't sound right.

[1stmustang]

I have a 2015 V6 mustang.

I attached a zip file with all the sounds that it's making.

1st sound is when I first started the car with the hood up and walked towards it.

2nd sound is when I left the phone on top of the engine and recorded as it idled and as I gave it some gas, you can tell there is a pulsating sound during idle that definitely wasn't there before.

3rd sound is accelerating down the road.

4th sounds is more accelerating while passing cars.

I'm curious if anyone here knows what it probably is by the sounds that it is making or even if you can chime in and say you really don't know.

I did have some body work done on it due to an accident so it's possible something went wrong there, at first when I got it back I didn't notice it but it's become pretty noticeable after less than a month. I just want to have an idea of what it might be before I tell them I think they did something wrong and curious what would be causing these sounds.

Sounds like a cracked exhaust manifold or cracked exhaust pipe. Won't lie, the 1st video sounds like my Toro Personal Pace lawnmower.

Had the same sound on my 2001 mustang v6 ended up being a cracked wield on the manifold. Removed the manifold and got a shop to re-wield the connection to fix the crack. Being newer car would guess this is something loose rather then something broken but it can happen.



First thing is to identify which side of the car it is louder on. Then get the car in the air look for carbon build up it should point to back to the leak. While the car is up check for anything lose on the exhaust.
