new catback system

i just picked up a used catback system. its a dcsports and i was wondering if i would need to do any welding to put it on. or if i could just directly bolt it on. i ahve a 1997 civic hx but the exhaust was on a 2000 civic hx

Well hmm If its catback its bolt-on but u have a 97 and u got a 2000 u sure its gonna fit properly i hope so but i belive there diffrent. Sry not sure
