was just curious on what my different options were with making sure i wont get a cel light on for replacing headers that eliminate the cat... its on a 98 civic 1.6 sohc thank u

 

O2 sensor simulator

 

yep. O2

 

most headers should have an o2 bung on them and then you can get a universal cat on ebay for like $30 and theres an o2 bung on the backside of that, so you should be ok. thats what i did and ran into no problems.
