Car exhaust noise when idling but not when driving.
Had connector from manifold to exhaust replaced a few months ago but still have noise.

Check the exhaust header bolts, they will sometimes work loose and fall out, due to expansion rate differences between steel and aluminum.

Otherwise raise car, put on heavy glove and pass hand close to exhaust trying to feel exhaust pulse and leak.
