Turbo Exhaust Housing Cracks

[Enilator]

I took my exhaust housing off and found cracks BIG SUPRISE, but i wanted to get it fixed while i had it off and i went to 3 different welding shops here in town and they all said get a new one. So my question is where can i get a new one, and are they all only made of cast? Is there other material options?

I welded mine,and yeah welding cast is different than welding regular steel. Well it cracked again next to the weld. I got a new exhaust housing for $70.00 Try Majestic turbo for a new housing.
