I have been trying to get one of the 4th gen OBX exhausts from EBay from SSAUTOCHROME. Keep missing. What exactly are the differences between these two pipe sets? The 5th gen sets are plentiful and cheaper.

i got one of those kits from ssauto and i like it a lot. mine came to me and on the wrapping it said for 97-99 maxima. i thought that it was the wrong one but it isnt. the only thing i had to do to mine was have an O2 sensor bung welded into the piping. other than that it fit great and was on the car in under an hour.may be different for you since you are a 97 and im a 00. just my 2 cents
