Okay, I had exhaust leaks before, but now my duals are completely welded together, and I'm seeing condensation on the ground under my car in the areas where the welds are. Am I still having exhaust leaks??

 

You could try using a stethoscope to listen at the welds. That method is often used to pin point noises under the hood and could probably be used in this manner as well. How close is the pipe to the ground?

 

if you have access to a lift or can swing by an exhaust shop, put it up and run your hands near the welds/ along the piping feeling for free flowing hot air. a little more convenient for those of us that didnt go to med school. <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />
