If I were you I would just wait until you could get Dougs or TTI, I did the cheap header route and it was horrible, and everytime I would scrape it would push up on the headers and loosen the bolts on the collectors, SUCKED!
I have these now: http://www.summitracing.com/parts/HED-78050/
They're horrible, but I needed something cheap at the time, now that I have money for an upgrade I'm looking at the TTI headers. One question though, I'm no expert on headers...whats the pros/cons between 1 7/8" and 1 3/4" step...
So if any of you have seen side profile pics of my car (you can actually see it pretty good in my signature), you can see the header comes down real low...I almost ALWAYS scrape on any type of "edge" (say from dirt going to pavement)...and I've read that shorty headers interfere with the stock...
