I don’t know since I have Lehmans but make sure you do the exhaust exactly per specifications or you may void the reman warranty if you got them from Cummins. Nice engine! You might try Tony Athens in CA. He is very knowledgeable on them.

All kinds of info on Cummins exhaust tight here. Scroll down a little on the left of the page. I'll be running a 5 inch dry stack.
