Is the install different on all wheel drive platforms than RWD? My buddy said something about dropping the subframe, but I can’t find any information on the AWD platform

 

Not sure about the subframe but I feel like I looked into this a while back and some of the headers won't fit the AWD because of the drive shaft or they require modification (bending/denting of the header so it doesn't hit the shaft).

 

It has been confirmed that PPE and ISR will fit awd models. I can't speak on the install on awd with confidence, but I believe its the same process, driver-side needs to disconnect the steering column to gain clearance during install, passenger side is straight forward.
