You get what you pay for. Decent but does need modification to.
For the price you can't beat them. The welds are ok and the bends and sizing are fine. Flanges aren't too bad they could use some filing down of a few burrs. Literally none of the o2 bungs are usable though the sensors either hit the other header, the engine or the chassis. You will need to cap them off and weld new ones on in better spots.The bad part is the inner diameter of the pipe has almost no weld penetration whatsoever which may cause a failure in the future so I suggest having this welded before installing.Also the placement of the o2 bungs is absolute garbage. The rear (post cat which you don't need anyway, there are no cats) o2 sensors will not fit at all without 90 degree bends and one of the pre cat o2 bungs is literally touching the other header. How you could possibly make such a mistake during manufacture is a mystery to me. Luckily it's not too big of a job to have a new one welded in below it.
