What are you running now? I might be willing to trade mine...otherwise af-performance is selling them for 535 shipped. (through clubwrx.net) http://www.af-performance.com/ You'll have to call them because they don't list them on their website.
are you looking for just the can or the cat back? ebay is your best luck.....i know someone who is selling a magnaflow axle back...pm me about this if interested!
It'll also help if you stated if you drove a 2.5 RS or a WRX. In your avatar, I cannot see the hoodscoop. The white is too lucient and magnificent that it blinds me.
