Exhaust Flex Pipe Leak

The small flex pipe that is about a foot long in between the y pipe and the first muffler is leaking. Apparently it is a dealer only part for about $500.

Anyone else have this problem or know where to get it cheaper?

I believe the "first muffler" you are refering to is the catalytic converter, and that pipe comes with it, why it's so expensive. Have you tried Rockauto.com?
