All ZL1's beware!!!

Judging from the first photo with the string hanging out, I'd say this proves beyond a doubt that your car is a female and she is having her monthly visitor.....

Just give her some space, understand her mood swings and hopefully in a few days, she'll be good as new and ready to ride again.

@ 5593 miles and I see the strings in mine. :'-(

I havent taken mine to the dealership yet as I just saw it.

Looks like a bird was building a nest in your exhaust

It doesn't effect me any really but now that I know its there, it will. Plus given the fact that brand new NPP exhausts don't look like this as I had a 1LE and it was perfect...I will post pics tomorrow

Just checked mine, didn't see it at first then looked closer and it's coming out way far in the back working its way forward. 1800 miles...

I wonder if GM knows this and will release something so we are about to get it warrantied with no issues from dealerships.

Warranty is covering it, new exhaust will be here tomorrow. Installation is Wed.

Well.. There have been hundreds of us with convertible top issues and it took well over a year for the first TSB to be published.

Check the part numbers to see if you're just getting the same muffler. We are curious to see if they (GM) actually are giving you a fixed part or just the same one that you will see fall apart again. Keep us posted. Thx

Will do, I'll ask them when I go back for the part #.

Just got back from track day at Buttonwillow and noticed same issue... Should I bother to take my roto fab kit off before taking it to dealer?

I would say yes if you don't want any hassle of any sort.

Hmm... I noticed some 'steel wool' coming out my second pipe from the left the other day. All the other pipes are clear. My car is in storage. I had put it up on floor jacks and was taking pics of the car on jacks and noticed the stuff coming out the pipe. I was going to write something here to see if anyone knew what it was or if it was a serious issue. Guess I don't have to now. I'll take it in to the dealership when she's out of storage. I have just over 3000Km on my ZL1.
