My first downpipe *pics*
I was using the internal gate from a .48/.60 T-bird T3 so I had to cut the cast exhaust housing in half and weld my pipe on. Where I cut the housing is not even close to circular, here is a pic of the pipe kinda tacked up. I went to the local exhaust shop and called 5 "custom" welders in my area and none said they could weld cast to mild steel. What a bunch of pussies. Keep in mind this is my first time welding and I'm using a crappy fluxcore welder 
I flattened out some spare exhaust pipe and flattened it and made 2 pieces to fill in the gap on each side. Here are the finished pics (minus the O2 bung)
I know it looks like crap but it's all sealed up

the welding needs work.
should have practiced on scrap first.
welding to cast is also not such a hot idea unless you preheated it and cooled it properly. which i doubt you did.
props for giving it a try though, i hope it stays on for you.

I don't think that will crack, it will just fall off LOL...I think he may of been smoking crack when he did that lol.
But I'll give it to you for starting out trying to weld cast.

Re: My first downpipe *pics* (beepy)
problem is that cast iron and steel have slightly different expansion rates. This means that the thing will crack pretty quickly. You should support the downpipe by attaching it to the block in order to avoid damage to your engine when it falls off.

I hope its not a load bearing structure in your turbo setup </TD></TR></TABLE>
It's a downpipe, so probably not. Just make sure to have a flexpipe downstream before the cat and it should hold. Otherwise, throw another layer of slag on top of everything and JB weld it smooth.
