o2 sensor extender to fool CEL for racing header...how?
 

I know each stock header has 2 o2 sensors...one before cat one after......But the racing header has only one o2 sensor port... installing them means getting rid of 2 downstream sensors which will trigger ECL.... People told me using o2 sensor extender can get away with the ECL... I am wondering how??? Anyone has some detail to share??? Thank you..
