I just purchased a 2017 Ram 2500 with 17k on it. I've never owned a Cummins with the EGR and DEF systems on it. The last diesel I owned was an 06 and I had installed a FS-2500 bypass system and really liked it so I've been looking for one for this truck but now there seems to be a lot more options to choose from. My question is are there any systems that people on here are running and how do you like it?
