Same as ALL of the '07 engines... DPFs, new technology. The new 07 CATs have a spark plug, ignition coil, and fuel injector in the exhaust system. The DPF is an oxidation catalyst as well as a particulate trap. An electronic exhaust system with inlet and outlet pressure and temperature sensors to trigger catalyst regeneration.
Oh, and a closed crankcase, too... no more draft tubes.
