This may be a dumb question but does DP's and aftermarket exhaust ease the stress on turbos

No......
A properly re-done system will flow air with less restriction. This will INcrease the temp delta across the turbine and INcrease the power output by the turbine. Thus, the turbo now does more Work; as it's creating more power.
The exact increase would be more difficult to quantify, but it would actually increase the "stress" on the turbo.
As mentioned below, a proper IC WILL decrease the work done by the turbo, as the pressure drop through the IC will be decreased.

That's at a given wastegate duty cycle, though. IMO, you can reduce the dc to compensate for the
increased efficiency, you'll have lower temps with no pre-cats, and turbo longevity will improve...
