[QUOTE="YJ928, post: 425415, member: 18583"] I'm swapping out my 4.2L and going with a reman 1991-92 4.0. I think I have everything I need except the header pipe. My 87 doesn't have a cat so I don't need the flat plate on the end of the header pipe that's available for that year 4.0. On the other hand the 93-95 header pipe has a flange that widens. Should I get the 91-92 pipe and cut off the plate or get the 93-95 and cut off the flange? This forum isn't letting me upload the pictures to show the difference. Hopefully it will allow me to post the links.
