Have the exhaust system check for restriction-

May be an exhaust leak before the catalityc converter, check for a cracked exhaust manifold.
There may be an engine problem causing it to run way too lean, possibly a misfire.

The engine may be running too rich and in combination with an exhaust leak cause combustion to take place in the exhaust pipe.
