Polished y-pipe with teflon coating
we sent a couple of these off to the port/polish company we deal with. they polished the inside of the pipe and then had them teflon coated, these 2 are both already spoken for but i have more on order so we should have some extra cores to be able to turn them around for you guys if your interested. the teflon coating was tinted with a gunmetal color on these.
i forgot to snap pictures before we started but i'm sure there are some floating around on the board, i'll snap some when the other new ones arrive here.
after polishing...
after teflon thermal coating...
by the way, the shavings did not burn like normal magnesium, they must be an alloy mixture were assuming.

Beautiful, I guess I will be the first to ask what if any gain does porting and polishing, along with coating them do ??

price is yet to be determined (gotta see how much the teflon coating will cost us as these 2 were samples)

I'm no airodynamic engineer but did you know that a rough finished surface is more efficient for airflow than a smooth surface, mostly because of the surface tension of liquids adhears better to smooth parts than rough ones, you might want to sand the inside of the coatings off.
