i have a 98 honda civic Lx...in which i am about to install some headers...i have the headers and the catalyic converter...is there anything else that i will need for installation

 

possibly a o2 simulator

 

Inline Four=Header....V8=Headers. But thats ok. And besides some wrenches and gaskets...nope.

 

haha, you beat me to headers

 

who cares..if u have alot of miles on ur car, might as well just buy a new o2. taking the o2 sensor off might be very difficult and u could possibly ruin it and u'll have to buy a new one anyways.

 

gasket, a jack/jack stands, and some wrenches.

You will get a CEL from the new cat and header (because of the added flow), and to correct that you need any o2 simulator.

^ but the universal one. If you want more info on o2 simluators, google it or Search it on here
