Wow, what a piece of crap! I was all excited to put it on whe I first got it. the old one came off easy enough, but the new one wouldnt go on. One of the holes didnt line up, ther was a crack in one of the primarys that I had to get welded, and the header had to get faced because it was warped. Thats 3 major defects that makes this header not worth the money. The header was about $350, and to get the crappy thing fixed is costing me at least $300. You can get better elsewhere.

Why didn't you just give it back they would have given you another one,or your money back,maybe it was one that sliped thru the cracks during the inspection process,they don't usually sell crap,but that piece sure fit's that description...........50iddy

I'm not the first person to have a problem with their headers.
