AAMI will keep on repairing my car until its fixed, i dont give two flying pigs. just the flanged parts mark, the welds we checked on the middle of the pipes that were butt welded didnt have any leaks. basically they just have to heat up the welds enough to melt it and cover the holes. as for the cat side, they have to use another flange as far as i'm concerned. thats already giving u enough sxxt doing the running around.. and with that kind of quality on the welding job, better redo a new one
