Dear trichard,

Hope you're well and stay so. Check things - especially sheet metal - exposed to airflow.

Among these:
(a) heat shields on: (1) the exhaust manifold and (2) on the catalytic converter.
(b) exhaust system hangers.

A piece of loose metal - or plastic (e.g., grille, etc.) - exposed to airflow may start to resonate at 28 mph. But if metal heats-up, the expansion may just be enough to disrupt the resonation.

Hope this helps.

Yours faithfully,

Spook
