Long tube headers
I have a question for those familiar with long tube headers on a 99-04 mustang gt. I bought a set of flowtech headers and o/r xpipe from a guy for $100. Good deal right..... They were unused but he purchased them 2 years ago and never put them on. When I got them home I realized the primaries at the flange do not look typical. They are square as opposed to the normal round ones that match the ports on the head. I attached the photo. Does this seem right to anyone.
If you can't fix it with a hammer, you have an electrical problem.
