center,

the

>>Starting about 2:30, I proceeded to cut the bolts holding the Y-fitting to

remaining

>>cat turned in to a real chore as the two were welded together with rust.
>>At eight o'clock, frustrated, I packed it in for the night.
>>
>>Sunday morning dawned rainy and dark. Not the ideal working-on-the-bus
>>weather. The first thing I did was get the Y-fitting off the headers.
>>This required a copious amount of elbow grease, and a few strategic blows
>>from a mallet. Once separated, I then had to take the y-fitting in side
to
>>the work bench in order to get the rusted bolts out. Putting the flange
of

>>punch and a mallet. Next came separating the cat from the old muffler. I

bolt,
>>being careful not to hack into the cat flange. A chisel and mallet were
>>used to bust out the bolts once the flange was cut away.

>>A word about the Dermal tool. If you have on, you know these little
>>buggers are great tools. But you also know that they eat up cutting
wheels
>>for lunch. If you don't have one, Home Depot has a 51-piece kit, with the
>>flexible extension, for something like $79. Worth every penny. But make
>>sure you pick up extra cutting wheels -- and the small wire wheel, that
>>does not come with the kit.

>>After separating the cat and old muffler, the next step was to clean up
the

>>appears to have been something other than original. There was exhaust
goop
>>liberally applied to ALL mating surfaces, probably from a failed attempt
at

>>Dermal tool, with the wire wheel, turned out to be a great advantage.
>>However, in retrospect, a bench grinder or drill with a courser wire wheel
>>would have made this an even easier task.

>>Finally, at around four o'clock Sunday, I could install the new parts.
>>First came the new muffler brackets, then the new muffler. If someone has

>>again in retrospect, the muffler needs to be bolted strapped to the
>>brackets, then installed, because the way I went about it, it sure wasn't
>>easy. However, once bolted up in place, attaching the cat, J-pipe,
>>Y-fitting, and tail pipe were cake.

>>I'm certain a more experienced Vanagon owner would have made much shorter

a

the
>>bullet and just purchased new everything -- y-fitting, j-pipe, cat, O2
>>sensor, muffler, brackets, straps, and tailpipe. It was not an
>>insurmountable task, and I feel great having tackled it.
