i am looking for a good catback for a 91 crx w/ a b16a in it. i searched and no one mentioned if it actually works or not.... it already has a dc sport header but the piping is stock and i didnt' know if they would bolt up to a catback manufactured for a d series rex. i'm sure everyone has ran into this...

 

Quality, larger, mandrel bent piping will help with a good muffler.
