Focus-central.com has them for $169.00. I think their prices on the website are different from whats in the Focus mag. I bought their Eibach pro kit plus for $639.00 which was the advertised price in the mag, but like $759.00 on their website. Anyways, best I could find cause I did a lot of searching for the same thing. Hope that helps.
I couldn't tell you how it handles, because along with that kit, my catback has been sitting in my garage also. Just haven't had the time lately. I'll post my opinion of it when I get it all installed though.
