kind of vague on removing things, like taking the starter off before the cat. how to get to the sensor disconnects, was a good effort, but little detail on how to remove items.
Theta, do you have the torque specs for all the bolts in the x-pipe installation? The other sections call out the torque specs, but this one doesn't. Thanks for posting this!

If you can write a how-to on this subject, you can most likely answer my question. I just recently bought a 2014 Z51(Approx. 6500 miles at this point) Someone switched the OEM mufflers for Flowmasters that have no NPP type of closure. The AFMs are still there. They are not working, presumably because the ECU is getting no signal from them. At the dealership (No one wants to trade) they gave me a quote for returning it to stock. The quote included replacing the cat back pipe. Question: Why would I need to replace the cat back pipe? If the answer is, "You said return it to stock. The cat back isn't stock.", then would it possibly be workable to leave aftermarket catback in place and return the muffler back to stock? If the answer is, "I would have to see it" , if you can, tell me what to look/listen for. I appreciate any help you can give me. My goal is to make the powerplant operate the way the GM developers intended.
its been awhile here but i wanted to share this information for anyone looking
i replaced the OEM lower exhaust manifold stud with ARP part number "ARP Stainless Steel Accessory Studs 400-8019"
i bought them on Summit https://www.summitracing.com/parts/ARP-400-8019
