V6 Flex Pipe Failure post catalytic converter

Anyone have a good independant mechanic in Mass that is familiar with Touaregs?

My 2004 Touareg, which is a V6 and has the dual cats down to a Y and then has a flex pipe to the 2nd cat.

The flex pipe has failed, and of course I have to replace the whole thing for $1000 in parts (2 cats) plus labor to drop the engine. I can swallow the 1k, but the 2k in labor I hear floating around really blows.

I am gonna try to at least get someone to remove the cat and weld on a new flex pipe, but I suspect resistance as this is "messing" with the emissions system...

Searching around for this, I see a few mentions and this seems to be happening to a lot of folks the last 6 months or so. Anyone do any hack repairs?

Of course my car is 7.5 years old and has 86,000 miles, why couldn't this have happened 6 months ago...

Number 10 (Porsche Parts list, same idea) on the diagram, flex pipe is the piece below the 15 nut on the diagram.

Had an indy shop pull the header and cats, weld on a new flex pipe.

$600, mostly labor, much cheaper than the 2-3k+ the dealer was quoting me.

Going through the same issue on my 2006 v6, which isn't even a week old of owning. Dealership told me the replaced the exhaust, come to find out nothing was replaced and 5 days after buying, the flex pipe has a huge hole and loud as heck!!!
