cobra making popping sound?

I also posted this over on the SVT forum. When I make the hard left up into
my driveway, the car makes a pop sound, almost like I ran over a soda can.
Sounds like it comes from down by the tire area. Anyone ever have this happen? I'm not sure what it is. It may be something the 03-04 cobra's only do. Whatever it is it's annoying as hell. Hope it's nothing major.
