Just ordered my stock header today. Going to make this a good winter project but have some questions. I am planning on getting a coneeng collecter and putting that on and just welding in some SS pipe to get rid of the cat and run that on my comp werks undertail exhaust... but here are my questions.
A) What if I kept in the o2 sensor? would it help the idling problems you guys were having and/or help performance at all?
B) If I were to keep in the exup in that should keep the volume down at idle right but would it be worth the fab work to integrate it into the SS pipe ? also if I did this (keep the exup) would it take away most of the performance gains?
