I am a mechanic so it’s hard for me to say someone with absolutely no skills that this is easy. But watch YouTube I will say everyone is worried about the egr exhaust bolts. But one video he sprayed them and soak them. I had sprayed mine each time I drove the truck and every morning for 4 days. Than another video a guy said drive the truck get it hot than when you go to take them out hit the socket and extension with hammer to loosen them. So I also did this. They all came out with absolutely no problem. I did have to take off my intake cause I did the ccv and disaster kit as well. And these bolts did not get sprayed. And one did break! I was able to get it out with wd40 and pb blaster and tapping with hammer. To drop dpf I sprayed the hangers with pb blaster used a pry bar and they pop right off. Remember when taking that off you might miss a coupe connectors so take your time! Also the back of dpf I had two broken studs and one so rusted that I had to use a grinder. After got it out I had to take a drill to my existing manifold cause the rusted bolts closed up the holes. Currently I left my dpf tank in the truck. I plan on removing it but I don’t have a reason yes!
Make sure to read all instructions and again take your time. I’m currently having issues updating the mini max cause I didn’t do it before install. But spe hands down was amazing the products everything was perfect besides the intake. The mass air flow sensor didn’t fit and to clean the metal shavings I used brake clean and it melted there spray paint on that one product, everything else i believe is powder coated. I know it’s not part of this kit but the cp4 disaster kit make sure you tighten hose clamps I did not do this and it cam off so I had to take upper and lower intake off on the side of the road and lucky the truck didn’t burn down. But I would say that was my fault for not verifying!
