[Jerry]

I replaced the stock muffler in 2019 with the Vetus you described and have had no issues with it 
Catalina 320 1998 #500

There is a second muffler in the transom compartment (where the steering gear lives) fastened to the hull low on the port side.   I don’t have a picture to confirm it but I think it is one of these >   https://vetusmarine.com/product-category/exhaust-systems/mufflers/

I reinstalled the new muffler on some door seal tape for cushioning of the vibrations and believe this quiets  it and will extent its life.

The seam around the base where the top is glassed to the bottom eventually cracks and the exhaust pressure will push out water and fumes through the cracks. There have also been cases of cracks developing where the hose tubes go through the muffler wall.
