Hey guys. Lately when I take off, say from a light, I’m hearing a chimmie-ing rumbling sound coming from the front of the car. Anyone experienced that before or know what the heck that can be?

Thanks

 

I've dealt with/am dealing with the same thing. First was the heatshield from the Y-pipe covering a disconnected pipe underneath. Repaired that, a few weeks later heard it again. This time it sounds like pieces of the catalyst have broken apart and are jingling around in the cat.
