1. You mean the same stock one that uses insulation between the piping and the SS heat shielding covering it's entire length.

The stock one runs significantly cooler on the exterior.

If you are smart you would wrap any non-OEM Y-pipe (ANY regardless of "coating"!) with a good thermal wrap.
This saves adding a tremendous amount of heat to the oil pan and engine bay!
No amount of airflow is going to pull enough heat away either. Also it's not like the piping is sticking into the airflow anyway. It's tucked up as close to the oil pan and subframe as possible therefore making a perfect convection oven to radiate it's heat too.

2. If you "follow all the proper procedures" when using a thermal wrap it really is not very harsh to the piping underneath. After 1 year "my piping" (beneath the wrap) looks the same as the day I painted it and wrapped it.
