It's Steeda's 22mm bar. I ordered their 21mm kit and got this one instead. I called and asked because it seemed a little beefier and my little plastic caliper said it was 22mm. The person I called had to call their warehouse (or someone else) and verified it was 22mm. He said they were going to being adding it their site but that was last year and its still not on their site, so who knows. I like it, works well big improvement from going to no bar to a 22mm 
Big improvement. Did you ever figure out to move the brackets toward the ends? I beleive you'll end up cutting the exhaust hanger off the cradle & mount it to the body. I remember seeing the cars w/o bars the exhaust hanger was on a little bracket welded to the cradle. On mine the exhaust hanger is mounted to the bottom of the unibody= the floor plan. I'd also mask off & paint w/ semi gloss or flat black your over spray.
