You have lots of options in that price range. Hedman, Flowtech, Hooker, and Summit all have headers around $150 or less. I personally have Hooker Comps, but they dont fit with power steering(unless you have a bracket, but I chose a manual conversion instead). Most other headers are the same way unless they specifically say they work with P/S. Also, Tri-Ys mostly have 2.5" collectors while 4 into 1s generally have 3".
PAW is a decent place, but dont buy any of their "house brand" stuff. I broke one of their brand new head bolts before getting to 65lb-ft and stretched two others. The bolt heads were marked as grade 8 as well. I got some ARPs and there is no comparison(smooth threads and truly grade 9 or better).
