Thanks guys ... she will go untouched and uncoated for now. I don't have the time/money left in my budget to order another housing, so the .7 A/R on the turbine will have to stay for now for development purposes. My 3" piping for the down-pipe back arrived a few days ago ... waiting on the 2.5" piping with turbine flange an transitions. I will keep everyone updated with piping progress.
