what headers Y pipe work
I have an 89 firebird formula with the 305 Tbi. right now I have mac headers and exhaust. I am going to replace the 305 with a carbed 383. Do I need a different set of headers and y pipe or do the late 80's motors still use the same headers as older motors. If not what can I do for headers and y pipe that will still line up with the rest of my exhaust. Thanks
