[T3] Muffler talk

[Dave Hall]

Access isn't too easy with the engine in, and you need to split the lower
joint where the muffler fits to the lower heat exchanger, which can be
simple or near impossible without damaging it, depending on how rusted
together the lower heater outlet joints are.

Heat may make separating these joints and the exhaust nuts easier.  

Are the old (lower) heat exchangers still serviceable?  If so, it's probably
not a job I would reckon to do until I needed to change the muffler anyway.

In theory, you can remove the lower heat exchanger while leaving the muffler
attached.  Expect difficulties with the nuts on the front studs and the
joint mentioned previously.

*With all this talk about exhaust part 'n pieces, I believe I may have found
two German OEM heat exchangers, in their original boxes.  All the
insulation, shields, bands, levers, flaps, etc. seem to be present.

Question:
1.  How difficult a job is remove the old ones and install the new ones?
2.  Is it relatively "EASY or DIFFICULT" to do, with the engine in the car?
3.  With two skilled "wrenches" working on the job, (on jack stands ... NOT
on a lift) how many hours might it take?
4.  Will we (probably) need a "fire wrench" to get the old ones off?
