Stock exhaust query... no, not about size diameter
This is going to be a dumb question... I am doing some exhaust rerouting work, is the stock exhaust piping behind the cat stainless or plain mild steel? If it I want to Mig weld sections of new "aluminized" steel pipe to the stock pipe, do I need a different type of wire than your standard steel wire?
Thank you to anyone with fabrication experience who might have an answer for me.
