All the bends are mild steel, not aluminized though they are very shiny surprising. The longer straight pieces that look to be aluimized are, I bought that tubing locally. Wire is .035 flux core from Lowes, Lincoln brand wire.

Made this piece. Took a 3" pipe and ovalized it, and it fit the T25 flange, but I couldn't ovalize it short enough to use and the 90* bend off the turbo fit. So I made a piece that's a lot shorter and does the transition.
Basically cut it in 4 spots so I have two flats, two curves, then pliers/hammer/repeat until it was the right shape. Took about 30 minutes to make it the right shape, then welded it all up, used a carbide bur to clean up the inside a touch, and then surfaced it. It still needs a bit more surfacing, but it's close. Didn't warp that bad welding it surprisingly. Material just wasn't flat to begin with
Gotta shorted the DP studs, then start the downpipe piece.
You can see two flat spots here. I fixed those with a hammer in a bit.
Fixed
Pipe fits perfect

I unbolted it and still have it. I may sell it down the road, we'll see.
