Feedback on ZEX kit for 2001 Mustang GT

I did on my 2000 GT Auto. It works great. It takes about 1 hour to and hour and a half to install. I only had it on my old 'Stang for like 2 months. The bottle still has it's first use of Nitrous in it. I am selling it for $500 shipped. E mail me if you're interested. [email protected]
