Looking good.
Be sure you do not have any loose or ready to come loose welds, or pieces of metal,, those will be injested by the turbine wheel & will damage it.
Heat wrap will speed up the process of rusting out your up-pipe & the welds if they are not a high grade of stainless. Stainless 409 grade rust' 304,316 etc are better grades.321 being the best,,, but is very pricey.
I would paint it w/a high temp black spray paint. I use it on my Syclone turbos & it works fine.
