I'm looking for an external waste gate setup, prefer Grimmspeed up pipe, the newer the better. Let me know whatcha got 6512744656
I saw a 38mm vband for sale here: http://mnsubaru.com/threads/2006-wrb-wrx-w-6spd-swap-part-out.47445/#post-780278 They are ~300 new and the vband's are hard to come by used. If you search long and hard (heh) enough, you'll come across a GS up pipe eventually...good luck EWG FTW!
If you're still looking I'll be selling my blouch 20g xtr, GS ewg upipe/Turbosmart vband ewg, and no name uel headers...lemme know
