Always check for any damage after welding has been done. Also check inside vehicle for damage to such items as carpet, inner liner, etc. Always have a class C fire extinguisher and a bucket of water available during any welding process.

This is a protective oil based coating used in the manufacturing of mandrel bent performance exhaust tubing. This is not a problem and will disappear within a very short period of time after the exhaust has reached normal operating temperatures.
