Decided to stay home and install the exhaust system in the driveway. If you are doing a complete exhaust system install do not watch the You Tube videos - mainly because those are not 2011 or newer vehicles. The front DPF catalytic converter has to be cut out of the vehicle. No easy way to just twist and wiggle it to come out. Take a sawzall and cut in front of the hangar and the two pipes will just come right out. Also be very careful with the electrical connections when trying to unplug them - very fragile especially the DEF tube. Yep, broke that one for sure...
I hope that I don't ever have to re-install the factory system as the little sensors and connectors look expensive. Did I say that I am pretty much a bull in a china shop. The front catalytic converter has little grains of catalyst falling out everywhere - which I originally figured was the culprit of my limp mode and non-warranty failure. The last time that I checked it was a $1275 part to replace and you would have to take the crossmember off to do the install. So 3 hrs. labor plus parts = too much for a non-California truck.
The front DPF sensor was very dirty and the rear one came out clean looking. this is a heavy exhaust system so you should have help when crawling around underneath your truck. OH and all the nuts are metric, except for down pipe clamp nut...
