Short answer, they don't.


There were a lot of changes from the 12V and 24V to a CR engine that were done for NVH initiatives and emissions compliance. The result is things change, sound just being one of the many.

Diff exhaust manifold setup, difference in injectors and pressures and how many times they fire during the cycles are the major reasons.

The common rail injection system is a big difference
