disclaimer, i have a custom exhaust so it's length is not the same as a stock exhaust's
overall, header seems to be pretty good quality
the donut gasket i ordered didn't fit, so sorry if anyone purchased it already
assembling the exhaust kinda sucked, the slip fit joints weren't perfect and required a lot of muscle and 2 sets of hands to put it together. also, my car's kinda low so positioning the header in from underneath was a b*tch. i ended up having to put the rear wheels on ramps and then re-jack up the front to have enough room.
the problem i ran into was with the test pipe section. it was too short to match up to my exhaust but the exhaust shop i took it to was able to extend it out. btw, it requires welding.
had my car dyno'd today. numbers are a bit higher because the tuner advanced the cam gear to 35 from 30. but before that, it was peaking at 258-259. the only different mods i have now from my last dyno are the headers (plm vs weapon-r), a skunk2 fuel rail and a p2r throttle body spacer. pink line and bottom numbers are from today's runs, blue line and top numbers are from my old dyno.
overall, pretty good gains. install was kind of difficult (but it may just be because my car's too low and my exhaust is custom). performance for the price can't be beat (paid ~$400 for my dc sports headers, ~$700 for my weapon-r headers). and i don't know if i'm just deaf from the dyno'ing but my car seems quieter and the fumes don't seem as bad.
lastly, i'm not sure if the p2r throttle body spacer or fuel rail adds any hp but i think the weapon-r has more power than the plm. however, it's not enough for me to switch headers back so expect a fs thread on my weapon-r headers soon.

side by side. the pipe set up is kinda different. 1-4 and 2-3 vs 1-3 and 2-4 (i think).

weapon-r (i had a custom cat built, b/c i thought it would make my car less quiet, this will be included in the sale as well as the test pipe. it's matched up to my custom exhaust so it will have to be modified, but at least you won't have to mess up the test pipe)
