Eric,
Thanks for the feedback, much appreciated. Interestingly it was Dustin @ SLP that insisted the FAT part of the pipe location for the O-2 sensor, ditto on the 10:00/2:00 position, not looking to debate, just want to get it right the first time, looking to install the PC-5/Autotune setup on my D-7, (no turbo)
It would be easier for me to copy your 0-2 location, wouldn't have to mess with the heat shield.
Just ceramic coat the pipe and can. On that turbo motor the faster you can move the exhaust to the turbo and the faster you can get them to exit the better off you are. That would probably control under the hood temps much better as well. If it were me I would probably consider ceramic coating the hot side of the turbo.
