I think the deal on the muffler is they don't make them anymore. I tried to get a hose made for my daughter's T/A because that particular hose was leaking. They couldn't save the muffler. I see lots of cars without the muffler. Both my cars still have that hose with the muffler, the four speed doesn't leak, but my Y88 doesn't have a working A/C so I'm not sure about it.
Now that I posted this, someone will post where to buy the hose with the muffler
