I have a set of XS Power headers I'll be installing soon in my AWD, and have a question. Along with the headers I also have a PCM modified Oil pickup tube and just ordered modded A-arms along with drop struts. Is there any advantage/disadvantages installing the headers while I'm doing the Oil Pick/Drop? Or will it just be a b!tch installing the headers in a AWD no matter what. I figure doing the Oil pick and drop at the same time will save me some time in the long run but was thinking with some extra room while doing that the headers may be a little easier.
