I received my DPF Delete pipe, it's a 4" pipe. Is there any special tools that are needed. I did the whole inspection thing and can see that the 8 bolts on the DPF are easy to remove but the sensor looks like its a b**ch to get out with out having the truck up on a lift. I got under the truck and used a wrench to try to get the sensor off but it felt like the sensor was going to break off and I didn't want to damage it so I stopped and jumped online to ask the pros. What is the easiest way to get the sensor off w/out using a lift? I sprayed some stuff to loosen the bolt up but that didn't work either. I'm going to give it another go after I hear some advice if it doesn't work there's a mom & pops muffler shop down the street from my house that'll do it for me.
