Exhaust leak in Hawaii

[vip808]

Nope, I actually inspected my exhaust because I just got that service reminder in the mail and at MYGMLINK to check your exhaust at 25000 miles. I only have 16643 miles.
It's rusted through (there's a hole) The last time I brought it in to the shop (8/19/05) I asked them to look at it because it looked really rusty for a brand new truck and it sounded noisier. They told me that it was normal and that it was ok. Is this ok?
It can't be from a rock because there's no damage to the bottom. This is in the rear on the weld seam. I would recommend everyone to take a look at there muffler before the 25000 mile interval.
