I think you need a better picture of the overall setup and where the water is coming from.

The problem with these muffler endtank design is that it is just stamped steel w/ a rolled edge. Sometimes they weld it shut, but if it's weeping water out of the edge (and not from the tips) then there is a way for moisture to rust and cause a leak later on.

It may be perfectly fine now, but depending on usage you may be replacing the canister or rear muffler sooner than you wanted.

The first mufflers on the market 15-20 years ago often were all mild steel w/ coating, and the resonators would have to be replaced often since any defects in internal welding would cause them to leak and rust through prematurely. Modern exhausts are stainless steel and less prone to rust, but it still happens as the methods of manufacturing are still the same.
