I called around a couple shops today to find someone to put on my headers; just for a laugh. The normal going rate is $55/hour. One place said to leave it over the weekend and they should have it put-puttin by Monday. Using the typical 8-10 hours labor I've read on the site, that puts their estimate at well over $400, and some places in excess of 600. I didn't pay half that for the headers!!
So I don't know if I'll get 'em on before the Dragon. At least I got my brakes fixed.
