I decided to have a look under my car, after noticing the sound of my exhaust was changing over the past few months. Well, I noticed a small hole where the connector for the b pipe and the b pipe join. I believe they are welded together. It's right on the 90 degree angle where the connector meets the b pipe. The hole is about 1/4" wide. Maybe smaller.

I inspected the rest of the pipe, and though it's a little rusty, it's really in pretty decent shape. If I had a welder I wouldn't even be posting...But is there anything I could use to close this hole? I could take it to a buddy mechanic and have him do something with it, but i'd rather just do it myself.

Here's a ghetto example of what I'm talking about, if you don't understand.

Note: Just an EXAMPLE

 

in the ghetto we use JB weld

 

I'd say the cheap options would be muffler mender or an exhaust repair wrap you could get them at any hardware store for 5$, or just go to a shop and have them repair it, shouldnt be to much money to get them to weld it back together or replace that little part.
