And the bolts screw into a water jacket. Not exposed to exhaust gas temp. Threads might hit 250F, bolt head a little hotter depending on mixer design.
Again, Ski is right on. 905°F is max turbine outlet temp. per Cummins on a CPL 1975 330.
I think the highest I've ever seen on any 6 Series marine Cummins is around 1000°F
