So I did the muffler delete and sometimes when I turn the car on, or have the car in reverse ; I hear a rattling sound coming from my exhaust.

Has anyone experienced this before?

It's Almost as if the tips are touching each other to make that rattling sound. However, when I hold the tips, the sound doesn't stop which makes me know that the tips are not touching each other making that sound.

The rattling is very intermittent and It just stops on its own and doesn't come back when it feels.


Anyone got any idea what's going on here?

 

Heat shield maybe?

 

Maybe some loose slag when they were welding in the bypass pipe?

 

I'd bring it back, get taken apart again.

 

Are you in Ontario, Canada? Or Ontario, California?
