I have two newer Chevy Duramax Diesels and there is zero smell in the Cabin.. riding behind the Truck is a different story.
I think the smell depends on the exhaust routing.. I won´t do a hood stack for sure and I probably won´t do stacks at all.

Also my fuel tank will be between the bed rails and not in the cabin anymore.
I hope this will help with diesel smell too
