yeah i have an 02 civic lx and i wanted to get an aftermarket header but i know the cat is in the header and its obviously an obd-2 car so im assuming if i just went ahead and installed the header its gonna think i dont have a cat (which i wont) and throw a code and it will be a pain in the *** afterwards...

any suggestions?

thanks
