I'm currently driving a turbo diesel from 2007 (early common-rail, no SCR system, but does have a DPF).
This vehicle did not come with a conventional muffler - it had a dinky little "resonator" at the rear. I learned that a muffler is not required on turbo diesel exhaust, because the turbocharger itself is the noise-mitigation device. The replacement exhaust I put on it didn't even have a place to connect a muffler.
All legal. If you have a Turbo, with no Muffler, don't worry about Bears...
Turbos and Mufflers (and Bears, oh my!)
