I received my new Eberspaecher exhaust last Thursday, and today I
started hacking out the old stuff. The cat to resonator bolts are
thoroughly rusted into the collar on the cat. I've chipped away all the
loose rust and heated the collar to dull red heat with an acetylene-air
torch. The preload springs were not enough to budge it, so I have
whooped on it with a big hammer. They are holding tough. Any
suggestions would be greatly appreciated.
On another note, Should the muffler clamps be installed in contact with
the muffler itself, or would it help to put a strip of fiberglass cloth
between the straps and the muffler? The can always seems to rust where
it contacts the straps. It's also possible that the glass cloth would
make it worse by holding salt water.
