Inexpensive exhaust system?

[Skunksmash]

Is anyone here aware of a somewhat inexpensive exhaust system that I can buy slowly but surely, over time? For an 87 350 2wd truck. Something that I could install myself, like the ball and socket types. My exhaust is starting to rot off of there, and I could really use a new one.

I've been looking around but they seem to want quite a lot of money just for some hollow tubing. I was hoping someone here might have run across something out there, as you guys seem to come up with all kinds of websites I had no idea existed.
