Oh then you should know the drill.
Saws all out all the pollution control garbage, big exhaust, egr delete and put a mild power tune on it.
Then you wont even notice the 3.73 to 3.42 gear change.

In my diesel I am going from 3.42 to 3.21 and from 31 to 32 inch tires.
After I rework the cross over pipe, go from 1.75 to 2.5 inch. Replace a few feet of 3 inch pipe with 4 inch exhaust pipe. Replace the stock torque converter with an after market one with slightly higher stall. Then turn up the injector pump I wont notice the change.
