Fix or replace SLP's 2 on the left muffler?
As for the stainless thing, those are made out of 409 stainless IIRC, and after 15 years and if it was exposed to road salt, it's not uncommon for a factory muffler to start rusting out. I dunno how that thing got split apart so bad, but the rust on the seams and the overall finish of the muffler isn't terribly surprising from what I've seen on my own vehicles.
so far my slp muffler has stood the test of time. perhaps the original ones from the late 80's early 90's were a little better
