Getting ready to install the Sinister EGR delete and the solid piece up-pipe. Any durability issues with these?? Been waiting for them to jump out of the box and onto the truck for a couple years and it ain't happened yet. So next week, it's flush and wrench time. Oil cooler also. Reason that I ask about durability is a Youtube video I just watched by a guy named Randy Johnson that made the claim that installing the delete and solid pipe would end up cracking the "Y" pipe .............."every time".
