Hello auslancer! Im in desperate need of answers!
I recently bought a RPW 4-1 Header system for the Lancer CH 2.4l , Everything was going smoothly till we got the exhaust off and realized we only have 2 o2 sensors not 3 like the extractors and Hiflow cat have.
On the New Extractor / Hiflow cat, there is 1 o2 sensor hole on the top of the new header, just before the downpipe there is another o2 sensor hole, and on the hiflow itself theres an o2 sensor hole.
On the old exhaust / cat, there is 1 o2 sensor hole on the top of the old header, and 1 02 sensor on the cat.
So currently we are very stuck with what to do next, hoping I can get some help here, or be led in the right direction.
