Holts HL 1831579 Gun Gum Exhaust Sealant 200g

I used this on my broken pipe at the connection after the catylac converter to seal around the entire pipe before compressing the pipes together with hanger wires. I needed to use my car, so I couldn't let it set over 24 hours. About 12 hours in, I started my car and no more exhaust leak, no more horrendous noise. My exhaust was quiet again and I could hear my engine running. I'm amaze how good this product worked. It came in a nice container that will keep the remaining sealed for future use.
