From what I've seen the mid section etc from a coupe will work on a 4dr....
the thing that I would say though is that getting the Pacesetter exhaust because it's cheap isn;t the way to go. I got one and it was the worst POS I've ever spent my $ on for my ride. I spent about the same and ended up 5months later spending real $ for a Quality cat back exhaust.
Also this was for a 93 DX Sedan....
