When I tow, and I tow quite a bit (another 2000 mi. trip coming up soon), I frequently have to use WOT or very nearly, and 8-10 hours/day of that with any add'l noise is a situation to be avoided.
Because the OEM muffler assy. lasted as long as it has, and it's darned quiet, I'd like to acquire something at least as quiet, and preferably as durable.

I had run this "Commercial Vehicle" muffler in my '89 Aero shorty and liked it well enough. It looks like a cheap universal muffler in the picture, but it's a lot heavier than it looks: 11 lbs.

I run the big Walker in mine also. towed with it for several years and is as quiet as the OEM. aluminized and almost exact same size.
totally agree Al, important issue after 8>12 hrs on the road, not to get out of the van with a muffler roar headache.
the big rear compartment in the Aero makes for a road noise boom box already without muffler howl.

I replaced all this tonight, and I have to admit, the muffler has no perforation (other than the two drain holes). It appears to be constructed of a 400-series stainless, and although the heat shields were rusty and ready to fall off, once I peeled them off, the muffler casing looks in decent condition.
As I was definitely hearing hissing under load on the highway, my current best guess is that Khan was right: the flex pipe must have been leaking.

I replaced the flex pipe on my Aero about two years ago. My wife was ready to get rid of the van thinking that it was about due for the scrapyard. (She knows little about cars) After I replaced it, she won't drive anything else. It's a '94 with about 250K miles and still has the factory exhaust, except the flex pipe.
