Re: VP TMD 22 muffler

We just went through this replacement process a few months ago. If you're willing to spend the money, probably the best option is to have a new one fabricated in metal or fiberglass so you can continue to use it as a step. I wasn't able to find anything off the shelf that would work for that, and in the interests of time and money, we went with a Vetus. Specifically, we ordered a model LSG75 and then added the SET0004 connection (because the two connections are different sizes on our boat, but the mufflers all come with the same size on both ends). I think one could just as easily order an LSG90 with a SET0003 and swap the connections as appropriate, but Defender has the former combination in stock and doesn't stock the latter.
It was a real pain to get the exhaust hose to bend in such a way that it will connect to the muffler, but with a little application of heat and a lot of choice words, we got it in. I was initially concerned about the strain the hose continuously applies to the muffler, but it seems fine. We replaced the exhaust mixing elbow at the same time with a stainless one so that we hopefully never have to touch this system again. It is hard to retrain your muscle memory to avoid stepping on the muffler!
