Do you have the NPP rattle?

If you have Dual Mode exhaust (NPP) please answer whether or not you have the rattle/buzz.

If you answer Yes, please include in the comments how many miles were on your car when you first noticed it.
If you answer No, please include in the comments the mileage that you have when answering this survey.

Thank you for responding. I want to get a gauge of how many have NPP with/without issues.

My issues appeared at 500 miles, but overall GM has resolved this issue for new cars coming off the line.

Sledge, I haven't seen any confirmation about any fix online so far. Any sources of the cars coming off the line?

2300 miles. Never heard any rattle. Never take it out of "sport" mode though and I have the V6.

No idea when mine started. Couple weeks before I took this audio recording.

Also if new cars coming off the line have the issue fixed, why are they having a hard time fixing the older ones?

I do, noticed it as soon as I got the car home at 100 miles. I mainly notice it when I cold start when the car is in stealth mode. Then it goes away when the car warms up a little bit.
