exhaust leak?

OK so I was washing the 6 the other day barefoot. I started it up to help dry it and when I put my foot under the pipe, I felt a puff of exhaust. Looked and saw a weld. Just for giggles I did the same to the other pipe. Sure enough there was a leak there. Question, is this normal or is it just my bike. I have only removed the left side pipe once to see how easy it came off. Before I go back to the stealer, I'd like to know.

I'll check mine, but it may be to let condensation out.

There is a weep hole for condensation..
