Most people that want a dual exhaust on their crxs have an exhaust shop make them up.
Theres no company that manufactures a pre-made dual that I'm aware of for the crx.
May I ask why duals?I am assuming that you are going for the bling right?
I ask that because if you are looking for a performance boost outta this its a waste of $$$.
Its all a look(bling) thing.
