need a bit of help plz

i just found out my headers have a HUGE crack in em. I have a 98 civic LX, and was wondering if any aftermarket companies make headers for it...cuz i remember somebody saying no companies made em for the LX, but im not sure.

also, what else, if anything, would i have to replace/modify when i get new headers on? i like cars...jus dont know too much about em

thanks in advance for any help
