Exhaust Question...If You Know Maybe You Can Help Me Out!!!

There is a Skunk2 MEGAPOWER Exhaust that I want to put on my Eg 4-door....the only problem is that the models they list it for is as states: "1992-2000 CIVIC 2DR EX & Si/4DR EX ONLY" And its just my luck I have a 4-door 1993 Honda Civic Lx...Is there a way to make it fit and get past the fact that mine is an Lx??...Is there a real big difference in my Lx an a Ex that it cant be made to work? Let me know it be a big help.....Thanks
