Replacing Y pipe on 04 4.7

Hey guys! Hope everybody is doing good! Ok... My question... Can I install the new Y pipe with the 4 O2 sensors already in place and just plug them in when its its in?

Yes you can. I have lowered and lateron installed the Y pipe with the sensors in place without any problem.

Yeah, only take care that you dont damage the connectors or wiring when putting the Y pipe in place.

Re: Replacing Y pipe on 04 4.7

I will be super careful with all the oxygen sensor components. Are there any torque specs for the bolts going from the manifold to the Y pipe?
