What is the difference besides cat location between these 2 headers? I have a cracked d16y7 header and want to replace it. I was thinking about swapping it for a y8 header. I know the 2nd o2 sensor is further back. How difficult of a task is it to do this swap? I don't want any check engine lights either.

Thanks

easy swap, just extend th o2 wires

 

Cool. I'll give it a shot. Thanks!
