i agree witha bove if you have tinkering ability and good with a welder (mig/tig) then they are inexpensive and can be made to work
i had these ( from ss auto ) well stil do but they had to come off after the flange blew off the driverside manifold and also found the driverside crossover split about 8" along the tubing seam
they are a copie of the ATR headers which are in use on many stage motored GNS
they never gave me the 60fts i was used to but they did perform as good if not a little better than stockers at the top (see sig) the headers themselves are nicely done , the flangers to the head are nice , the turbo flange needs work just to be able to bolt the turbo on , but the crossover and the psuedo v band flange connections they tried to use are less then optimal I had to cutoff and rewelded to correct the turbo mtg flange , had to redrill a couple of the flange holes on driverside do to poor placement of the upper bushings (not too bad) , mofied the crossover flanges a little , had to locate vband clamps (they arent cheap) , find spacers so v band clamps would actually work (atr had a gasket )
i had mine in leak free (quiter than my stockers ever were ) , but if you push your car like i do any header will require some attention on a weekly basis and these china headers are no differnt , they seem to split around those v band flanges due to weak tig welding that didnt use any filler rod so plan on replacing all the cheap flanges with good flanges like what atr used on theres
and if you had a shop make a crossover you could save yourself some headaches on that fit
OH and youll need a downpipe designed to be used with the atr style heders , stock wont work, nor will the ones that use the stock elbow, and some 3" houstons wont fit either , i have mease and atr downpipes and with those there isnt any isuues
a better fitting set based on another design was on ebay a few weeks ago that claimed to bolt right in but they have the same flanges and arent proven yet for durability
