I got 2 of these to make a custom driver-side header for a 5.0-swapped BMW E30. I already had one made, but it was ugly and poorly designed. The pipe welded good after cleanup -- I didn't try welding it with the dark finish still on it. I also used a very unconventional welding method: stick welding with 1/8" 6011 rods. We ran out of welding wire a while back, and I've been using what we have for the time being. Turning the amperage down and making faster passes going vertically allowed for it to not burn through.
The only thing that turned out to be a nuisance in the end but isn't too big of a deal, is all the metal shavings from cutting it sticking to the oil inside that the pipes are packaged with to prevent rusting. It would be best to clean them out before cutting them.
