I ordered mine directly off the gibson website. They only list a cat-back system for the 93 model, but it fit fine on my 94. It was a little more than 300, including shipping, for the aluminized steel one and like 100 bucks more for the stainless steel one. I have the alu. steel and it works fine. I actually really like it and think it is worth the $300. Best part is that no welding was required so i installed it myself.
