I need a header!

I have a Alpha header that has a leak which causes a backfire when I shift. I have tried welding it up but it seems to crack again, think it has to do with poor original metal. I hate the bang but dont want to buy new. Dont want to go back to the stock cast manifold so I'm asking here. Anybody gone to a turbo or supercharger kit and have their old stainless header just collecting dust? Anybody?

Thanks

That's is for a Cobalt not a Slingshot. Look a picture number three where the exhaust flow apparently goes from the exhaust pipe back into the engine. Even if it was for a Slingshot not sure I'd buy from them. But thanks.
