Hey gang. I had an issue with my car cover snagging my tail pipe on my exhaust muffler from a good wind over night that weakened it to the point I have a clean break where the pipe joins the muffler. After looking at the muffler, the metal is still in good shape so I started to think about Mig welding the pipe back on so I can support the exhaust with the tail pipe clamp again. I have some years welding but before I do it I wanted to ask if any of you have experience when it comes to knowing if I will damage any of the elctrical circuits with the car being a negative ground system. It may not matter yet I rather be safe then sorry.
