The crack on my exhaust

[n00b on demand]

So for a while ive had a crack on my exhaust right before the main cat. Took it into the shop today so they could take a look at it and maybe weld it. The guy called me and said its a little hard to get to and wouldnt be able to weld it...called the dealer for a price to replace and its about 550 bucks. So he said he could patch it up for me but its on temporary and it would leak again. This sucks....i was hoping that bad noise would finally go away. I'm letting him patch it up for like 5 or 10 bucks. TomsSvx, next time we meet you need to show me exactly where this crack is if the guy cant show me today if the shops too crowded....i need to see where i need to do future patch ups
