I have the stainless band clamps and they were leaking at every connection. Plus, with the collectors being cut short, there's no room for the band clamps because of the O2 bungs. I still need to add the driver's side cat and then probably get some of the joints welded up. Have you installed any of these XS Stainless headers yet Josh? They seem to fit well. I heard they are doing a slight re-design to lower the driver's side collector a little and will be offering emission's hookups again and a catted stainless y-pipe.
