Downpipe issues...

[Brandon Rogers]

This past summer I did some major R&R on my '84 Urquattro.  During that time
I did find a hairline crack in the same place that Jerry mentioned....at the
joint between the pipe and cast part.  I took it to a recommended (by
another welder) automotive welding guy here in Denver.  He drilled/shaved
the cracked part out and rewelded it.  I've heard of the difficulties in
welding this part, but he didn't seem to think it was a big issue.  The part
is now bolted back up and we'll see how it holds up.  Only time will tell.
(I did buy a used DP for a spare, just in case).  So my advice is to find a
good welder and take the DP to him and show him what you want to be done.  I
went to a few places during my search. Good luck.

I'm curiouse about this since my original one broke
just off in my hands when I went to pull it out of the
car. Did you have and header exhaust wrap on yours by
chance?  I'm blaming that for rusting mine out.
Luckily I had one in my pile of stuff.
