I would agree with Ron on the fit of the Dansk mufflers.  They fit like
stock.  I have installed many of these myself with minimum hassle (as already
stated, don't expect everything to go together smoothly when the rest of the
system and muffler straps are all worn out and rusty).

I also sell the S&S Header muffler for the Vanagon.  This is $120 and bolts
up with minimum hassle as well and has it's own tailpipe (you need to make a
small strap to hang the muffler from the stock mounting point but that is the
only difference).

I was not sure if I liked this muffler initially, because it is a little
louder than stock.  But I installed it on a customer's van about 4 months ago
and since then I have put a few hundred miles on the van running errands (the
customer told me to).  The muffler has a deeper, throatier sound, but you get
used to it and actually start to like it.  The muffler is installed on a '86
Westie with automatic tranny and all I can say is that it does take off from
the line better than my '91 Carat.  Both vans have the stock exhaust header
with my Carat having a new Dansk and the Westie a new S&S muffler.  I would
say the difference is quite noticeable (especially since the Westy is a good
big heavier than my Carat).  I am almost to the point of replacing the
muffler on my Carat with the S&S one (I wouldn't hesitate except the muffler
is only 6 months old).

Just FYI.

Thanks,
