So I got my stage 2 pure for my N55 and am concerned about the seating area of the wastegate flapper valve and the seating surface of the diverter valve. It is usually machined surfaces but the one I got both surfaces have been bead blasted. Should I be concerned about sealing or anything?

Just curious - brand new from Pure? Or you bought used?

this is brand new from pure. It will be replacing my current pure stage 1 and the stage 1 wasn’t bead blasted like this nor have I seen any other pictures out there like it so that’s why it concerns me
