Sounds like one of the exhaust heat shields is rattling.

My 100Q did this until I fixed it.  Look underneath the car
where the exhaust turns to go back along the chassis. There
are usually some cheap sheet-metal heat shields there, which
rattle when cold, then stop when the exhaust has warmed up.

You can either tap them with a hammer to make them stop rattling
or remove them completely.
