I live in the Portland Oregon area. In our area DEQ will not pass long tube headers even if you pass emissions level test. They say you can't relocate the cats. Are the shortie headers worth installing? Does anyone have dyno results or drag results.

No, shorties aren't worth installing (maybe a little better than stock) and you won't find many around here that run them because of that.
