what are our choices for long tubes? Of course MAC (which I hear are a PITA to install and are not that great) and then BBK which I have also heard bad things about. Why do they give the 87-93 guys all the choices? Arent there any other brands with a decent rep and easier install? 
They will warp because they have no single flange, and the non-coated ones will rust to hell. Stay away from mac headers.
Now I run BBK and the install and reinstalls are much easier with the single flange. Plus I opted for the JET-HOT coated ones.
