    i want to buy an Apexi WS2 exhaust system for my 97 civic dx coupe. I was wondering, since I have an aftermarket header on, would I buy the exhaust for the dx or the ex. ( since the dx is supposed to have the cat on the header.). This mite be a dumb question, but i want all my basis covered before I spend the $$$. Thanx for the help.

    Isn't the exhaust universal for 97-00 for Civics no matter what model?

    ok so you own a dx, but with your new high performance header, you have no cat converter? or no cat on the header, but are using an ex cat converter?

    Yes, I own a DX. I have some cheap ass aftermarket header on the right now, therefore, i no longer have the cat on the header like the dx comes stock with. It is not an ex cat, I have no idea what kind of cat it is, the exhaust shop threw one on when i had my skunk2 exhaust put on, but it is after the header now, like on the ex. My guess would be to get the ex system, but I want to know for sure. Does anyone know which one to get?

    Here are your options:

    Get a DX model if you want no cat converter, will bolt right up to the header with no problems.

    Get a EX model if you want a cat converter, you will basicaly upgrade to an EX exhaust setup. You will need a stock EX cat converter or have to custom and aftermarket unit to fit.
