I had to dig up the link so it took a little while.

Here's what I used on my '85 Westy for 4 years and really liked it.  I
actually bought two mufflers from this company:

Also a reference here:  http://www.vanagonauts.com/Recipe-for-Performance110.htm

It was a round 6'' Dynomax Super Turbo muffler length of which I do
not remember, but it sounded very nicely.  Unlike a glasspack muffler
these will not get ridiculously loud over time.  I've read about
people using longer bolts on the factory muffler hangers to make them
fit the slightly larger muffler.
