2004 Manual Gasoline Peace, mercy, and blessings of God be upon you. I have Land Cruiser headers, manifold and downpipe, without the last muffler (sold). They were removed and I had them on the roof for 10 years, and I just took them down from the roof. I don't know about leaks or welding. They were removed from a car before selling it. Contact via direct message or phone call. Location: Riyadh, and shipping is available.
