The metal in the exhaust system cooling down. As metal is heated it expands, as it cools it goes back or retracts to its orginal shape and size. It is not as noticable in cast steel as it is in thin drawn steel such as what the thin pipes and shields are made of.
I hope this answers your question. Good Luck!!!

Its totally normal. Don't worry about it. Most aluminum engines do that after being driven. Its just the metal contracting as it cools.
