The car once I park it after driving through the rain, there will be this 'tinging' sound which I would assume be the metals contracting since its cooling down. Is it possible that the EP3R with the less sound deadening [assumption] and while running could make thing ting into a banging sound? After all exhaust pulse and exhaust gas rushing through would change the sound remarkably.
