I've decided to try and go ahead with this despite the Aveo still not operating properly. So, today I gathered the components and layed them out to see what would need to be done to get this setup installed in the Paseo. Here is the layout I figured out.
So, I need to weld a block to the exhaust manifold. I believe this is 409 stainless steel. Does anyone have any experience or tips for welding mild steel to 409SS?
