GHANDl

hey guys im new to this just need some quick guidance if anyone has the time. I have a Honda civic 2001 LX 1.7 D17A1 i believe and im trying to get a new catback exhaust with a new header but the problem is most companies only make exhaust systems for EX model trims, where my LX the O2 sensor or catalytic converter is on the header itself where I might run into some problems when installing aftermarket exhaust. I've read somewhere that I could get a O2 sensor adapter wire to connect to the engine bay all the way to the catalytic converter on most aftermarket exhaust which is further away from the header on the piping. Can anyone confirm this for me or suggest what I could do to make sure i successfully install either a
Yonaka 2.5" catback system with a Skunk or whatever 4-1 header? Much appreciated
