GT25 vs 28 header cracking ratio

[M5-]

OK here is a quick poll for you. I'm trying to get a rough idea of the number of cracked front mount headers using GT25's vs the number of cracked headers on the GT28 front mounts. Theory has it that the 28 should make less heat and thus be longer lived for the same boost. So quick post of turbo type, header mileage, and boost.

GT25 - First header 500km CPR 10 lbs

GT25 - Second Header 2000km Powderlites 12 lbs
