is there a major difference? I want to put a catback from a ex on a dx and someone told me it wont fit? True? Not any mods need to be made to make it fit? Full catback

 

location of the cat is completely different the two are not the same.

 

DragIIcivic: I think that's only for the 6th Gen Civic.
I have a 95 EX and sold my exhaust to a friend who has a DX (5th Gen)

 

???

anyone know for absolute sure?

you can always look at his car, if he has a cat in his header, no, it won't work, if his cat is underneith, yes it will work.

 

anyone know for sure. Greddy told me its different but some people said a civic is a civic. Greddy says a 95 dx exhaust fits all 92-00 ex civic and si's but not 96-00 dx's. I don't know its frustrating. They said the pipe that connects tot eh cat has to be remade from a muffler shop it will not bolt up

 

uhhhh you have answered your own question

 

5th gen dx has a cat under the car like all the other civics, the 96+ dx has the cat in the manifold. So 92-95 coupe ex and dx exhausts are supposed to be the same, of course stock piping diameter is slightly diff't. All the fifth gen hb exhausts should be the same also.
