there are a number of issues with them,poor welding , manifold and flanges look like they are made from girders, poor and incorrect shaping of apertures , and no finished grinding i.e. inside of the pipes has more lips than jagger and welds where manifolds and flanges are joined has more bumps than the rocky mountains ,here are some photos but unfortunately they don't really shoe the extent of the problems, they are so bad I'm off to get the pipes sorted by a local steel works tomorrow
built with girders.
odd shapes
big lips
poor welding
overall poor quality don't be tempted unless you are prepared to have them finished by someone else[/img]
