I have recently discovered the JRD 7100, get the 4oz. can. This will seal
those exhaust flanges. Silicones and other types of sealants should never be
used on the exhaust unless the goal is an O2 sensor or Catalyst replacement.
Exhaust temps can get into that 1300f range (the pipes glowing red). If you
must use a sealant you need something to put up the fight.

Same thing happened to me with an exhaust system from a different vendor.�
Did not look quite lined up and leaked when I fired it up, so relied on the
extra gaskets and spray copper stuff to seal it up.� I would have much
rather had a set that lined up perfectly but needed the van ready for an
upcoming�vacation already planned.� Sometimes you just have to make do.

By the time you get underneath and are trying to fit them up you tend
to have an awful lot invested in the status quo...my experience anyway.

I got some 1.9l exhaust stuff from Bus Depot many years ago that
needed surgery.� Come to think of it I rather believe it was
Dansk.� It was a rush order, I was headed to Nova Scotia the next
day, and I spent the night doing whatever it was.� I wasn't extra
happy, and after the trip I asked to swap them for proper ones.� Ron
wasn't particularly receptive, and I understood -- he couldn't really
give them back to Dansk after I'd hacked on them.� In a better world
etc, but this is the world we have.� It certainly wouldn't have made
sense to blow the trip for this.

Perhaps this is how we absorb some of the life-pain of people who
have to spend their lives welding flanges on the ends of odd-looking
bent tubes times infinity.
