Truck has been running well, 414,000 km on it now. The exhaust did get noisy on it after a trip to Manitoba.
As I've just moved to a new town (Medicine Hat) I didn't know a cheap muffler shop and money is short right now but...I found some cheap muffler parts from Canadian tire. so I ordered them in and went at it last Sunday in the CT parking lot.
Doesn't look so bad here

But this shows the issue

Have a resonator in place of the cat, and that was still in good shape

Can't complain about the pricing, but without those part numbers Lethbridge CT wanted 4X the price.

So I cut the pipe in back of the resonator with a hacksaw, mounted the tailpipe and muffler in, and joined it to the rest of the exhaust with a $10.00 extension and a couple of clamps.

Seems to be solid, sounds much better.
Besides the muffler and tailpipe I needed the mentioned 1 7/8 extension pipe and clamps, 2 @ 3/4" bolts for the tailpipe/muffler connection, and tube of muffler cement (no gasket supplied). A regular hacksaw, some files, and a big hammer came in handy. I raised the truck a bit eventually for working room.
I did the same thing back in 2003 when I was a broke student and it lasted 5 years. Seems like the same parts.
