I started up my car today and heard a ringing noise and an "off" exhaust note. I listened and confirmed the oddity was coming from the exhaust, then went out with a friend. On returning I looked closely and found the welding from where the pipe goes into the main body of the muffler. This Kleemann unit is not even two years old so I'm a little disappointed to have it have a problem like this. Anyone have any suggestions on what to do or whether its ok to drive the car for an extended distance (like 20 miles to get up to MBAutowerks).

On a lighter note, now my car sounds like the many "flowmaster" equipped pickup trucks around here!
