Hi all, new here. Read a few of the threads regarding O2 sensor bypassing and etc. Everyone seems to keep acting as if there is only one cat on the 96-00 Civics? Mine has two... One in the manifold, and a smaller one welded in place down the middle of the car. I'm not wanting to replace the things. I was just wanting to buy a cheap header and pull off the rest of the exhaust (run it open)... However, I want my CEL to be working and off. Figured it was easy as throwing an O2 simulator in the bung hole on the downpipe... The pipe has an EX down pipe but that shouldn't matter if I'm scrapping the back half of the exhaust right?
