Exhaust front pipe broken, need help!

[MrOwl42]

The front pipe on my 1977 300d cracked right near the connection to the resonator piece. I looked online and then went to pep boys, after a while they found out that the front pipe was no longer made by anyone and they couldn't find any where to get it. They did find one place that has an alternate system that they say will fit, but it would mean replacing the entire system. I'm also planning on checking with the dealer, but I'm expecting high prices if they even have it. I used a trick I heard about using a tin can and some rescue tape to join the broken pieces, but I don't expect that to last very long. Does anyone have any other ideas?
