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.
Get a muffler for an 82 and up camaro or firebird.... thay are single inlet dual outlet and made to be mounted sideways just like the crx muffler.... they are a little longer.... then you can just take 2 90's and run them out the back.....
i had this setup for about 3 months.... while testin gout different exhausts
its nice... but looks a little dumb dince tehre is not an exhaust cutout on the pass side.... however if you are crafty I guess you could graft the cutout from another bumper onto your right dise and then it would look a little more like it was suposed to be there..
ps. the camaro "turbo" muffler" had a pretty mellow decent tone on a crx with a cat still on it.. .
