The right big CPL 870-871 is no joke. Tell you buddy to get ahold of Gearhead if he wants that cat to hang with that cummins

I can’t see how the Acert cat can hold a head gasket with that amount of boost, I threw my cat out in one of my trucks because to many headgaskets failures and it was recently overhauled and In the proses of putting in a 2250 with low km I got from a wrecker ,(put a new fuel pump on it) yes there are some who will think I took a big step backwards, worst case scenario it will drop a liner, if that happens I know it can be cut and shimmer and theoretically should be good for a long long time if done right, but am keeping fingers crossed that this one will not have that issue, I have big demons to slay getting the wiring to work I know that

That high boost doesn't all go into the cylinders. The Iva's bleed of cylinder pressure. That's why when you look into an Acert head its all soot like an egr engine is
