exhaust rattle? Video posted (oem 2 pipe mod)

[akkando]

I had the oem 2 pipe exhaust mod done a while back shortly after I got the car and it kind of had this rattle sound from the driver seat, but I didn't really hear it that much, was only at high revs, and I just wasn't very concerned.

Anyway my buddy the other day was taking some videos of my car and it's really obvious from outside the car when revving. It doesn't sound like any "exhaust rattle" I have heard in other videos. What do you think it is? Something wasn't tightened back to how it should have been? Something not right with the 2 pipe mod?

You can hear it at about 10 seconds in the video. Get the same sound when car does a fly by.

This persons car kind of sort of has a similar noise going on but not as much.

This is probably what it should sound like

The first thing that comes to mind for me when I hear exhaust rattle is the OEM x-pipe donut gaskets.

I had a long undiagnosed rattle from the front end of the car near the driver's side underneath my foot. The rattle would only happen on cold-starts during certain frequencies. When the car was in motion it wasn't noticeable.

Changed the donut gaskets and the rattle was gone.

This pretty clearly sounds to be coming from the rear of the car to my ears.

Someone posted about the same noise, could be the baffles cracked inside the exhaust.

Do a search and you should be able to find something here.
