Anyone know where I could find an exhaust for an 88-97 katana?

[Gandalf]

I'm looking for a used aftermarket 4-1 exhaust for my 1990 katana 750, anyone know where to find it? I've searched the local cl and junkyard with no luck...right now my only option is to buy a new vance and hines system on motorcycle superstore, which unfortunately is more than I can spend right now.

I found a yoshi system a while back but it turns out that its for a different year katana so the mounting bracket interferes with the fairings. I couldn't get the old pipes off so I had a shop swap the pipes, and they had to beat the crap out of the stock pipes to get them off, so putting them back on isn't an option. I.e. my bike is parked until I find another set of pipes.
