I'm going to install a Magnaflow exhaust on my Firebird, the original exhaust nearly fell off!

I want to temporarily mount it until I buy Headers and a Y pipe. Does anybody sell "universal" sections of pipe that will bolt up to the Magnaflow's Flange?

I think it's called a ball and socket flange, I can't seem to find anything other than this $90 Flowmaster kit. But, I only need the one side, and I don't want to spend $90 on something that's temporary.

This is the Flowmaster kit, I only need the side on the right I think, to mount to the Magnaflow kit.
