I've had a few, wish I still had em all but whatya gonna do?! I've never heard anything bad about a nwor header, just bad about their customer service, same as downey. I only ran my downey on an automatic truck so I don't really know what it did for it cause it came on it, but you won't be dissapointed in the quality. I picked my nwor up off ebay for around $120 I think, and I don't think I'd ever pay for any of em new.
