Greddy SE/SP Catback Exhaust

Hey there, my name is Alex, and I am looking to purchase a brand new or used Greddy SE/SP Spectrum Elite Catback Exhaust. After hearing it on my friend's car, this is the perfect sound which I am missing for my STi. I have called numerous vendor's but had no luck trying to find one, so if any of you are interested in selling your's please PM me, as I am really looking to purchase this.
