I've started a project with a 98 chevy SWB. I have a set of headers coming, but I'm unsure how to handle the four 02 sensors. I know I need to attach at least two of them to the headers, but which ones do I and do I have to get o2 extentions. If anyone has any info for me it would be great. Been a fan of hotroding a long time, but just getting into the building end of it. Have a lot to learn, but you gotta start somewhere.

 

depends on the style headers (long or short tube), if you're running cats or not and if you can tune them out. we need a little more info on the truck brother.

 

I think that we might need to move this post?
