well.. at least it's not *too* hard to grind the welds off, flip it round, clean it up, weld it back on.....
actually, sod that - take it back! :lol:
By the look of it the hanger is too long too, or,, does it just need bashing around the pipe a bit, looks from the pic if the hanger was tapped round the angles would be similar to the old pipe
hope you did not have it from Mr Exhaust they do not last long either.
