Tips on welding aluminized steel
I cannot find any U-bends in mild steel, but there are all kinds of places that make them in 90 elbows. I am sure one of these places can make you a 180.
Edit: Here is a place that does custom bending up to 8" pipe. Just tell them what you want and get a quote.

Use a mig welder.
I didn`t even think about it till I saw this thread, but my exhaust was aluminized steel. When I welded it together I did no surface prep
oh well it didn`t seem to hurt anything. I scuffed the edges with a scotchbrite pad and fired up the mig. I didn`t have any problems so as long as you clean the aluminized coating off you should end up with great welds.

The simple and better way is to use a mig or tig if you have one. 1/16" filler rod for tig and run the temp down to about 10 amps higher than your first amperage where a pool forms.

if you got a sand blaster , it would make quick work of the aluminum coating.. if you got a mig i dont think id even bother unless its real thick or giving a crappy weld. .. i just mig'd a peice of stainless to my aluminized x pipe.worked great.
Just sanded the coating off. O
n my old car I had a shop weld my exhaust, before I knew how to weld. It was aluminized steel and I am pretty damn sure they did not take off the coating and it held on well, had the car for two years until I sold it.
Make sure to wear a mask.
